Could you use drones to put plastic explosives on planes at airports?

Recent drone sightings make you wonder if someone testing the limits to find out what type of drone could they get close enough to wire a plane with with plastic explosives? Are they attempting to set up some type of terrorist act why are they entering FAA airspace at over half a mile in the air? Is there some type of drone that will attach itself to the whole of an airplane and take over its navigational control causing it to crash into say Trump Towers? God bless God

airports?
