RE: Pilot box
Yes, we have a 3' high chain link fence in front of the pilot stations. No, we've never had anyone injured while on the flight line (because all the errant airplanes that would've injured someone were stopped by the chain link fence)
We've had numerous airplanes, to many to count, take a hard turn on throttle up, or landing and end up in the chain link in front of the pilot stations, we have one fence pole, set in asphalt, that's loose because it's been hit so many times and we've never had anyone injured while on the flight line. Saw a 140", twin engined powerd giant scale airplane flown by a very experienced scale competitor kept from coming into the pits and spectator area at the Scale Masters qualifier at Phoenix 3 weekends ago by chain link in front of the pilots stations.
