I'm sure many in this forum have also seen the damage that even things as small coins can do when ingested into a turbine engine. When I was in safety school back in 1998, we studied an accident where a single ball bearing (wrist rocket size) brought down a Harrier jet (high bypass turbofan). I'm a bit concerned about what happens to our hobby when they actually do start shooting DJI's and similar sized objects at turbine blades. Those outrunner motor cases are a lot larger than ball bearings.
