Edmund,

The model must free itself which to me means no outside influences. So
my responses would be as follows

1) timing stops as the pilot freed the model, it did not free itself
2) timing stops as the model did not free itself, the pilot created air
currents to free the model
3) timing stops as it did not free itself, same as if the pilot dislodged
4) Once a model hangs it becomes part of the "building" like a light
fixture is part of the building. So you can steer from it but if you
hang on it then no re-flight.
5) No reflight for the model that collides with an already hung up model
as a hung model becomes part of the building once hung. Also a midair
collision I think by definition means both planes are flying. I would
not call a flying plane that hit a stationary plane a midair collision,
they would both need to be in the act of flying.

I think I may know where these last few questions are coming from. A
friend of mine (who was an official timer) ask me a couple days ago why
did John Kagan get a re-flight when his model was hung on another model?
The answer is simple, he did not get a reflight because his model hung
on another model. He got a reflight because earlier in the same flight
his model had a midair with another plane but luckily they both came
loose from each other and kept flying. The person I was talking to had
no idea that a midair happened earlier in the flight (the actual reason
why John was allowed a reflight). My friend had incorrectly assumed the
reflight was being allowed because Johns model became hung on another
model and John was somehow using the midair collision rule as a way to
get a reflight. That is not the reason why he received a reflight.
Hopefully that clears it up for others who may have been having the same
question on John's reflight. I was not aware there was some confusion
about his reflight as I knew what happened but I can see how people can
think exactly what my friend did since he did not know all the details
on that flight.
