You could make the floor foam blocks or a trampoline, but in concept it's very similar to the Skycam used for NFL games and they are very reliable. I've never heard of one coming down (and they have a lot more travel).

There's certainly been instances of cameras coming down and having near misses with players and referees. Those cams weigh a lot and are moving at high speed as well.
