I must admit, when I first saw GoPro cameras some years ago, advertised as the sort of things that surfers or skiers would attach to their equipment to get videos of themselves, I didn’t think too much of ’em. Glorified selfie machines, of little real value to the world. But damn if some people haven’t done some interesting stuff with them. Such as this video, with a GoPro on an aerobatic biplane. That is not new… but gyro-stabilizing the GoPro is new (at least to me).
GoPros and similar cameras have proven themselves sufficiently that a good case can be made that they should be prit near *everywhere.* Two on each jetliner wingtip… both looking inwards at the whole aircraft, one above the wing, one below. Two or so in the cockpit, watching the crew & instruments. One at the tip of the vertical stabilizer, looking forward at the whole aircraft. One in the nose looking forward. One in the belly looking down. Heck, one in the underside looking aft & down to record any Russian anti-aircraft missile coming in.
