FAR 91.119 Except when necessary for takeoff or landing,
no person may operate an aircraft.................................
.....
(c)... closer than 500 feet to any person, vessel,
vehicle or structure.

In light of the above regulation, would someone please
tell me how our 50 foot finish line is legal? All the
finish lines I have seen come within 500 feet of a
person (Charlie & his kids) , vehicle (his van).

Aren't we just asking for what happened in the UK?
