point 1:
I switched to free external view (CTRL + F11), followed by ALT + *, which changes your zoom-speed. ALT + mouse-wheel should also work.
Aeroscout already answered your second question, so i won't get into that.
@ VMFA-Blaze: Thank you :) I like the idea of parking in a bunker, that's why i included this scene. Unfortunately this only works for AI planes...
