AI 171 crash probe widens: Ahmedabad airport ground staff quizzed, phones seized, sabotage angle not ruled out

A multi-agency investigation is underway at Ahmedabad's SVPI Airport following the Air India AI 171 crash, which killed 241. Ground handling agencies are under scrutiny, with staff questioned and phones seized. The probe, involving AAIB, Gujarat Police, AAI, DGCA, and the NTSB, seeks to determine the cause, including potential sabotage.

AHMEDABAD: Ground handling agencies at Sardar Vallabhbhai Patel International (SVPI) Airport are under scrutiny by multiple investigation agencies as part of the ongoing probe into the crash of Air India flight AI 171 last week.The investigation, led by the Aircraft Accident Investigation Bureau (AAIB), is being conducted with support from Gujarat Police, Airports Authority of India (AAI) and the Directorate General of Civil Aviation (DGCA). A parallel probe has been initiated by the United States' National Transportation Safety Board (NTSB), bringing international aviation experts to the crash site in Ahmedabad."All personnel involved in ground handling operations for the ill-fated flight were questioned, and their statements recorded," said a source familiar with the investigation. "Phones of key staff members who cleared the aircraft for take-off were seized for further examination."A comprehensive, multi-agency probe is underway to determine the cause of the crash. Investigators reportedly obtained CCTV footage from airport premises and are not ruling out the possibility of sabotage. On June 12, Air India Flight AI 171, a Boeing 787-8 Dreamliner, crashed moments after take-off from SVPI Airport, killing 241 of the 242 on board.Investigating teams have since recovered the digital flight data recorder (DFDR) and the cockpit voice recorder (CVR). These are crucial pieces of evidence, which will help identify what led to the crash of AI 171. A CVR records cockpit sounds, including pilot conversations, alarms and sounds of engine and switches clicking.Read: Air India passengers stranded overnight at Delhi airport after flight encounters technical 'snag'The DFDR, on the other hand, logs hours of flight parameters such as speed, altitude, thrust, flap positions, autopilot inputs, acceleration, lift and landing gear movements. According to officials, the pilot issued a Mayday call shortly before the aircraft lost contact with Air Traffic Control (ATC) at SVPI airport.Officials from Boeing, the US Federal Aviation Administration (FAA), the NTSB, and UK-based aviation experts are now in Ahmedabad as part of the probe.The NTSB, in accordance with the international protocol, is investigating the crash independently due to the aircraft's American origin. This is the first time a Boeing 787 Dreamliner has crashed.The US agency, an independent federal body, is tasked with determining the causes of civil aviation accidents and recommending preventive measures.

Ultracompact fiber-tip sensor achieves high sensitivity in magnetic field and temperature measurements

Magnetic field sensing plays a pivotal role in numerous fields of medical, transportation and aerospace. The optical fiber-based magnetic field sensor possesses outstanding characteristics of compactness, long-distance interrogation, low cost and high sensitivity, which has attracted intensive interest. However, the fiber-based magnetic field sensor is generally affected by the temperature perturbation. Recently, although the temperature crosstalk can be effectively eliminated by integrating multiple sensing elements, it is at the cost of increasing the size of the whole sensing components, and the different spatial location of multiple elements could cause the measurement errors in the multi-parameter discriminative sensing. In a new paper published in Light: Advanced Manufacturing, a team of scientists, led by Professor Limin Xiao from Advanced Fiber Devices and Systems Group, Key Laboratory of Micro and Nano Photonic Structures (MoE), Key Laboratory for Information Science of Electromagnetic Waves (MoE), Shanghai Engineering Research Center of Ultra-Precision Optical Manufacturing, School of Information Science and Technology, Fudan University, China, and co-workers have developed an ultracompact multicore fiber (MCF) tip probes for magnetic field and temperature discriminative sensing.

Kevin Drumm — OG23 (Streamline)

On OG23, Kevin Drumm simultaneously plumbs the deep seas and tumbles through outer space. Incidentally, both environments are potentially lethal; the ocean’s pressure will squish our bodies, and the vacuum of the cosmos will tear them apart. Sounds pleasant, right? Drumm thinks the concept is worth probing. With a wry smile, he’s placed a broken-down submarine right in the middle of the album’s cover. Sadly, there isn’t a damaged spaceship on the other side, but the point is obvious: these sounds evoke uncontrolled motion, existential dread, and the ironic beauty within that which threatens our survival. To borrow a concept from Harry Sword’s tome on drone music Monolithic Undertow, Drumm has created a “sonic womb.”

Drumm originally posted these multi-dimensional meanderings on his Bandcamp page in 2022. The transitory emanations are singular within his extensive catalog, and thus the sounds begged for a physical release. Enter Christoph Heemann with his Streamline label and the mastering expertise of Drumm’s longtime pal Jim O’Rourke: the ghost in the machine is now alive and it has scratched its sinister signature into vinyl.

Situating any new release within Drumm’s oeuvre is an arduous task. Between his overflowing Bandcamp catalog and his physical output, he has hundreds of releases. Drumm’s vast body of work is also a multi-dimensional continuum, morphing based on his chosen tone generating apparatus. He delivers barely perceptible hum as seriously as he does meditative drones, agitated mechanical clatter, and punishing harsh noise.

Drumm can be withholding regarding the genesis of the material he releases, and this is the case with OG23. It’s clear, however, that he’s harnessed electrons to do his bidding. The tones slide around like multi-hued oil droplets on water or condors drifting on atmospheric air currents. Sounds enter the field of perception, alter course, and then disappear like whisps of vapor. As one element vanishes, more appear. Mid and low-register swarms provide a scaffold-like hum, like a fleet of airplanes performing a flyby or the rumble of a distant factory.

OG23 resembles aleatoric or generative music in the way its tones worm around and vanish. Drumm’s established a sinister calculus and dialed in the parameters. The fractalized patterns use his framework to writhe and take on new forms. Each of the side-long pieces corrupts Drumm’s algorithm with its own unique mutation. On the A side, a flock of robotic birds explores the Starship Enterprise engine room, whereas on the flip, the passerine beings search for home within the humid air of a subterranean cavern. Drumm is the mastermind behind both scenes, reveling in the strange harmonies he’s set in motion.

If you're setting up or upgrading a PCB assembly line, here's a comprehensive guide on how to choose the right SMT testing equipment for your needs.

1. Understand Your Testing Objectives

Before selecting any testing equipment, define your goals clearly. Are you primarily testing for manufacturing defects, functional issues, or both? Different types of SMT testing equipment serve different purposes:

AOI (Automated Optical Inspection): For detecting surface-level defects like solder bridges, misaligned components, or missing parts.

ICT (In-Circuit Testing): For verifying electrical performance and component values.

Functional Testing (FCT): For simulating real-world operating conditions and checking overall board functionality.

Flying Probe Testing: Ideal for low-volume or prototype production where fixture-based testing is cost-prohibitive.

Understanding what you need to test will guide the selection process and help you prioritize features.

2. Consider Production Volume and Board Complexity

Your production volume and the complexity of your PCBs will significantly impact the type of SMT testing equipment you require.

High-Volume Production: For large-scale manufacturing, speed and automation are critical. High-speed AOI and ICT machines with multi-board support and automated defect classification systems are ideal.

Low-Volume or Prototype Production: Flying probe testers and manual visual inspection systems can offer greater flexibility without the upfront cost of fixtures.

Complex Boards: If your designs include high-density interconnects (HDI), BGA components, or multi-layer boards, advanced AOI with 3D inspection and X-ray systems may be necessary.

3. Evaluate Automation and Integration Capabilities

Modern SMT testing equipment should easily integrate with your existing production line and MES (Manufacturing Execution System). Look for features such as:

Real-time defect reporting

Barcode/QR code traceability

Automated board handling systems

Remote diagnostics and data logging

Automation not only speeds up testing but also improves consistency and traceability, which is essential for quality control and compliance.

4. Prioritize Test Coverage and Accuracy

The effectiveness of your SMT testing process depends on the test coverage and accuracy. For example:

AOI should offer both 2D and 3D inspection for more accurate solder joint analysis.

ICT machines should be able to test a wide range of components including resistors, capacitors, diodes, and ICs.

Functional testers should simulate real operating conditions and measure parameters like voltage, current, and signal integrity.

A higher test coverage means fewer defects slip through to the final product — saving time and reducing costly rework.

5. Think About Total Cost of Ownership (TCO)

While initial purchase price is important, don’t overlook the total cost of ownership. This includes:

Maintenance and calibration

Fixture costs (especially for ICT)

Software updates and licensing fees

Training and support services

Choose a supplier known for reliability, customer service, and long-term support to maximize your return on investment.

6. Scalability and Future-Proofing

As your production grows or technology evolves, your SMT testing needs may change. Select equipment that is modular or upgradable. Some AOI and ICT platforms offer software-based upgrades or allow for additional camera modules, faster processors, or enhanced analytics features — enabling your system to evolve without total replacement.

Conclusion

Choosing the right SMT testing equipment for your PCB assembly line is not just about buying a machine — it's about investing in your product quality and manufacturing efficiency. By considering your production needs, board complexity, automation goals, and long-term scalability, you can make informed decisions that lead to fewer defects, smoother operations, and satisfied customers.

Best budget-friendly optical reflectometer

In recent decades, the rapid development of optical fiber communication (OFC) lines has required simple, reliable instruments for diagnosing optical communications. An optical time domain reflectometer (OTDR) is one of the most common devices for testing fiber optic links and identifying problem areas in fiber optic communication lines. What criteria should be used to choose a reflectometer so that it performs correctly and does not require excessive financial investments?

Reflectometer: luminous intensity

A reflectometer directs a beam of laser light into an optical fiber. Then, it measures the parameters of the reflected light, thus analyzing the characteristics of the optical fiber. This way, one can not only detect but also determine the location of any damage to the fiber optic line: a lousy receptacle or connector, a cable bend, light loss, poor splicing, etc.

This is a very effective technology, but it has two severe limitations. First, the reflectometer's probe pulse is reflected from all connectors, including the first one, which is why "lighting" creates a dead zone in which measuring is impossible. This problem is solved using an additional piece of optical fiber (launch cable) connected to the line under test. The dead zone is on this fiber, and the entire line can be tested. It is necessary to consider the length of the line that is supposed to be tested and select the correct length of the compensation coil; sometimes, the length can reach several miles.

The second limitation is that different types of optical fiber have the highest light reflectance coefficient at different wavelengths. Of course, the best choice seems to be the most versatile device that can operate in a wide range of wavelengths, for example, from 850 nm to 1650 nm. In particular, the VIAVI MTS-8000 universal measuring platform and a set of modules capable of solving almost any problem of fiber-optic communication analysis.

One must keep in mind that expanding the capabilities dramatically increases the cost of the device. However, these capabilities are not always necessary. More straightforward solutions are often sufficient for checking and even last-mile optical line certification, such as an optical reflectometer with the tester function and damage visualizer Greenlee 930XC-20C-UPC-FC.

The situation is similar to the dynamic range—the strength of the reflectometer signal and its ability to detect even slight attenuation of the optical signal. This can result in a severe deterioration in the efficiency of fiber optic lines on long, critical lines. Therefore, more expensive reflectometers with a wide dynamic range are used to check them. Generally, an OTDR with a dynamic range of 6 dB is more excellent than the loss of the longest optical communication line that the OTDR will ever have to service, which is sufficient for reliable testing.

These are the main aspects to consider first when choosing a reflectometer. However, many reflectometer models are on the market, and selecting them is not always easy. Fortunately, there is a simple set of questions, and answering them will give you a "portrait" of the device best suited for a specific set of tasks.

The right questions to ask when choosing an optical reflectometer

First of all, you need to answer questions about using your new reflectometer:

What networks and types of optical fiber will be tested (for example, multi-mode optical fiber or single-mode optical fiber)?

What is the maximum length of the fiber-optic link to be tested?

What measurements are aimed at (certification, troubleshooting, regular maintenance)?

The answer to these questions will significantly narrow the field of suitable reflectometers. For example, 850 nm and 1300 nm wavelengths are used for multi-mode optical fiber, and 1310 nm and 1550 nm are used for single-mode optical fiber. In the case of PON testing, wavelengths of 1490 nm and 1625 nm may be needed in addition to 1310 nm and 1550 nm.

If the reflectometer's main task is to localize damage, then buying an expensive device may be a waste of money.

However, if detailed diagnostics of a fiber-optic link and its certification are needed, professional reflectometers with a large dynamic range, small dead zones, and good software for processing reflectograms and generating a report are necessary.

It is also necessary to consider the aspects related to the device's operation. In particular, the size and weight of the reflectometer are directly related to the team's mobility. Devices with a larger screen (more than 5") are most often chosen for indoor work or as part of a mobile lab. Specialists use portable devices to work on city networks. Such devices must have waterproof housing and withstand a wide range of operating temperatures.

The minimum operating time on one battery charge is preferably at least 8 hours so that field measurements do not extend over two working days. The ability to upload data to the cloud for subsequent analysis and results processing will significantly save time.

Often, several instruments can be combined in one housing: a reflectometer, a tester, a damage visualizer, an optical spectrum analyzer, a dispersion analyzer, etc.

An important feature is the ability to expand the functionality and update the reflectometer software during operation, which means that a more expensive modular solution may be a more profitable purchase in the long term in some cases.

Bullseye: Hunting for Life at the Center of an Anoxic Sulfur Spring­­­

Dear AGU, 

            In the middle of a coastal wetland in Erie, Michigan, the “Great Sulphur Spring” stands out as a striking hydrogeologic feature. Here, karst geology has formed a circular sinkhole approximately 50 m wide and 13.5 m deep, venting anoxic and sulfur-rich groundwater. These modern-day extreme water conditions are similar to those found in Earth’s ancient seas harboring the earliest life forms. Our mission this day was to find out if the bottom of this sinkhole was inhabited by microbial mats: communities where chemolithotrophic and photosynthetic microbes live together in a thin layer overlying the sediment. Presumably, similar mat communities in ancient seas were responsible for oxygenating Earth’s early biosphere.

            To prospect for microbial mats, we used an underwater camera on a cable, hung from an inflatable raft. By stretching a rope across the diameter of the spring, we were able to pull the raft to the deepest point of the sinkhole, where the denser groundwater pools. Here, we dropped a multi-parameter probe to characterize the groundwater and collected water and mat samples for analysis. Footage gathered from the underwater camera shows purple-colored microbial mat “lawns” growing at the bottom of the sinkhole. Future studies will compare these mat communities to those found in similar refugia elsewhere such as submerged sinkholes in Lake Huron, sulfur springs in Florida, and permanently ice-covered glacial lakes in Antarctica.
