of touching down, I fell through the tops of skyscrapers. Is this
because (as a newbie, sad to say) I turned off "crashing"?

No...it's because there's no "runway" on the top of the building on which
you tried to land. It's a question of how the scenery is configured.

Some buildings do have "runway" surfaces designed into their tops, so that
helicopters can land there, for example. If there's a building you want to
land on that doesn't have a "runway" on top of it, you need to use the
scenery editor to add one yourself.
