At what point is the end of the launch?

Launch is to release, catapult, or send off; therefore according to para. 1 and reference to the starting time in 4.k.2, the end of the launch process (not to be confused with the end of the flight) is when the glider leaves the competitors hand (which is also when the time starts).

Can the launch handle be like a cross-bow?

Yes, the launch handle can be any configuration desired, as long as energy to launch comes from elastic stored energy and the launch handle is safe.

Does the elastic launch loop have to be a complete loop?

No, the elastic does not necessarily have to be a complete loop but it must have a loop.

Does the launch handle have to be hand held?

No, but the launch handle must be of a safe configuration. If there is any perceived safety hazard, the event supervisor may prohibit its use or the students' participation in the event.

Is their any restriction on the elastic material used for the launch loop?

The elastic material used to launch the glider must be a) elastic and b) of a safe configuration.

May the elastic material in the launch handle be metallic?

Yes, the elastic material used with a launch handle may be metallic as long as the supervisors officiating the event feel the application is safe for use.

Must the glider be launched from floor level?

Students, not the glider, must be at floor level (standing, sitting, etc.) when the glider is launched.
