I admit that I have been involved in these "low pass" competitions. Us
wind-up toy, propeller guys go much, much slower though. I will say
that flying this low to the ground has...well...some risks. There is
an old aviation adage that says says that the three most useless
things in flying are: runway behind you, altitude above you and fuel
in the truck. These guys are leaving a lot of altitude above them.

Oh...and the guy standing on the runway in #3 has balls!
