first idea:
catapult testplace - and if the "runway" is in top of a hill, it wouldnt be a crash to cross the trees at the end of this "catapult"
but at least:
thats only a place for starting ... no idea, where the plane come from, so they could only start and never come back
its not very rational, to dismantle the plan after each start, transport the parts to the platform, assemble the parts, make an new start and dismantle the plan again ...
so: where ist the place to see the surrounding aerea?
