This is how it will work.
1) All participants must register, as I want a list for the record attempt.
2) ONE person per engine. Each participant starts his/her own plane. This will be done for safety and simplicity. No helpers allowed - too much confusion.
3) No movement. I want the participant to start the engine, stand up and raise his arm, indicating that the engine is running.
4) This will be done on a row-by-row basis. Depending on the number of participants, I will set up rows.
For example, if there are 75 participants, it will be five rows of fifteen people each.
5) When I give the signal, the people in the LAST row will start their engines. When I see fifteen hands up, I will signal the next row and so forth. I will allow one minute per row before mving on to the next row. If an engine will not start, the participant should keep trying. If an engine stops, refuel and restart.
6) When all engines are running, we will quickly count hands - I will have a number of assistants.
7) The entire event will be videotaped by at least three cameras.

When appropriate, I will give a signal and all engines will be shut down.
Of course, the rules will be plainly posted at the Fly-In
