The Space Shuttle had a famous double sonic boom when passing overhead during re-entry. This schlieren flow visualization of a model shuttle at Mach 3 reveals the source of the sound: the fore and aft shock waves on the vehicle. The nose of the shuttle generates the strongest shock wave since it is the first part of the vehicle the flow interacts with. This initial shock wave turns the flow outward and around the shuttle. The second boom comes from the back of the shuttle and serves to turn the flow back in to fill the wake behind the shuttle. (The actual shock wave would look a little different than this one because there’s no sting holding the shuttle like there is with the model.) The other major shock wave comes from the shuttle’s wings, but, at least for this Mach number, the wing shock wave merges with the bow shock, making the two indistinguishable. (Image credit: G.

one of my favorite twitter accounts that is defunct now is it was this account called like Crazy Optical Illusions or something and they would just post popular optical illusions but edit them so they werent optical illusions anymore and they would just pretend and people would be very confused / angry in the comments

Skunkworks was great when everyone was just a bunch of raging alcoholics that showed up to work relatively on time
