It is some sort of bug, just like the invincibility bug/glitch when after you open up a kill streak where you hold a laptop(predator, rc drone, ac130...) then it will close right after opening and then you either run around with out being able to die or just like in this video he is controlling the laser from the reaper through his seights. It has only been done by accident. Possibly lag between player and host, the airspace full maybe and because of the lag he opens it up and then it registers the airspace is full and it gets put away and that happens, still not sure, could be wrong.
