The show sites are an accident waiting to happen for display pilots who don't have their aircraft under direct supervision at ALL times!
I've had many incidents with fans getting a bit too close to my airplanes while on site. In fact, one of these experiences I have always included in safety briefs with display pilots.
Concerns preflight inspection habit pattern development for show pilots.
Naturally, proper preflight is a pilot's best friend normally, but on a show site you need to go a step further.
I had a rule I never strayed from when on a working site with one of our airplanes.
ANYTIME the airplane was out of my personal sight for 30 seconds or more, I did another preflight.
This practice was proved out in spades one summer afternoon when I preflighted the airplane, then on a sudden urge (it was hot as heck that day) I ran across the ramp and grabbed an ice cold coke from a vendor wagon passing through.
The airplane was out of my sight for about 3 minutes. In that time, some child had left a stuffed animal in the carb intake tunnel under the spinner. Probably a kid being lifted up by a father as the carb tunnel on a 51 is pretty high up for a small kid with a stuffed animal
Coming back with the coke, I re-preflighted the airplane and found the animal.
Could have been a real problem had I accepted the first preflight and simply started and taxied out to do the display.
Rule 1 for display pilots working a show; preflight it of course...............but out of sight for ANY reason........preflight it AGAIN!
Another time down at Transpo in 72 I just managed to stop a kid from grabbing the rudder trim tab on Bill Ross' Mk16 Spitfire and trying to bend it to see if it moved! Lucky Bill had parked next to us that day.
All in all, pilots in the community look out for each other's airplanes pretty well. This has been true all through the years I've been associated with these people.
