That’s a transonic shock wave. It happens when you’re near, at, or going slightly faster than sound. All kinds of weird stuff happens in this range. At what airspeed in which that occurs varies based upon atmospheric conditions: altitude, relative air pressure, temperature and, humidity. That is to say, at lower altitudes, around 6*** KTS is enough to travel faster than sound. Higher up, where air is less dense, you don’t need to go as fast to out run sound. In that image, the air in the cloud is in a low pressure zone thanks to the shape of the airplane in the transonic range of speed. The sudden cooling of that air, as an artifact of the depressurization, causes the water in it to condense and form a cloud which is what you see, albeit, very briefly.
Trivia: Going transonic, F-15B's ASI goes nuts as the shockwave moves forward and intersects the pitot tube (it doesn't stick out the nose like a lot of supersonic jets). The fuel consumption also goes nuts - goofing around past mach results in really short flights. And rolling back the throttle past mach throws you into the harness really hard!

So, will this happen? https://www.cnn.com/travel/article/antonov-an225-mriya-rebuild-2022/index.html CNN) — For avgeeks, the destruction of the world's largest commercial plane was one of the key images at the start of Russia's invasion of Ukraine. In February, the Antonov AN-225 was attacked at its base in Hostomel, near Kyiv. "The dream will never die," tweeted the manufacturers when it was destroyed. Now it looks like they have stayed true to their word, with the company announcing that plans to rebuild it are already underway. Nicknamed "Mriya" -- Ukrainian for "dream" -- the massive plane was built in the 1980s to carry the Soviet space shuttle. On Monday, however, the Antonov Company announced in a tweet that the rebuild project had already begun, with "design work" already in the offing. While it had estimated repair costs, the company predicted a bill of over €500 million ($502 million) to get it back in the air, promising more information "after the victory."

The aircraft lost a bet in the hangar and had to wear a tutu on its next sortie. A lost side bet has it wearing a tiara, too. The pilot's callsign was Buck-something.
Yeah, pretty much. I had a former coworker that was into paper airplane competitions. He took it pretty seriously. The "longest flight time" planes were pretty amazing. They flew very slow.
