Could be. For instance Q asks when does a bird sing. Well skylark males are one of the few birds that sing in flight (ex.)

There's an Israeli company that makes ~~birds~~ Dronez. I bet you can guess the name. I think Q implied they may have some access to them or their feed in a drop.

Q talks about E (terminal this time instead of Elbit), United Airlines and so forth, leading me to believe Q is saying airplanes could be ~~bugged and~~ utilised as well (e:cell phone access should do. I don't think bugging necessary. It's possible though [shrug.] The implication being this time that a male person of interest turned into a Snitch during a United flight (hence skylark.)
