that's a really interesting idea. the biggest questions i have are.... 1. how much will it cost? for equipment, sensors, etc? 2. is anyone willing to pay for it?

If you don't want to ask anyone in particular, you can ask yourself other feasibility questions like: -how heavy will it be? will it affect the flight of the plane? -how much do current planes cost? how does that compare to the cost of adding a camera device? -how many people fly planes? how many planes do they have? -how often do people crash planes, and why do they crash? how expensive is it to fix? how does this cost compare to a camera that could prevent a crash?

my initial guess is that there is no feasible business model there, but what if you twist your idea around a bit? such as sharing videos of airplane flights? and modifying video equipment so that it could be installed on model airplanes? that could potentially be useful.
