Off The Wall Questions!!!!!!!!!!!!

Hey, I was the kid that aksed questions in school that made the teacher
wonder if they were in the right class so here goes:

1. If I built a large domed building, could I fly my helicopter inside
without a helicopter license? I know there is some debate about needing a
pilot license if you do not carry passengers - but in our state, at least,
you do need a pilot license to fly.

2. Someone told me that if you dragged a rope behind an airplane and it
touched the ground at all times, you are not actually flying according to
the FAA. Unfortunately, I could not find this statement in the FAR. I
guess this might be answered by the question of needing a license to pilot a
tethered balloon (with passengers)?

3. If I am in a glider connected to an airplane by a rope, and the pilot ot
the airplane controls where I go, and I never detach, why would I need a
glider license?

4. How high does Class A airspace extend?

Hey, it is Friday. The first question popped up this afternoon during a
practice autorotation. All the way back from the airport, the questions
kept coming.
