Hovercraft on buildings?

Update: I have also noticed that this isolated gravity affects aircrafts aswell, making take off a bit difficult and some weird skidding behaviour when close to a surface.

If you hover a jet for example close to a building and somehow knock the aircraft on its side with the bottom of against the building it will drag against the building till you fall to the ground, rather than be able to use the aircraft controls to propel yourself away from the structure and correct yourself.
