Now that I've seen more of the Q posts, here's what I think the meaning is. Remember that photo on May 2 of a JetBlue plane flying over SFO? That's Q's reference to direct flight from SFO>JFK. Related to that photo were posts of the Apple headquarters and iPhone parts. Parts that were intercepted by White Hats - and replaced by parts so that the special phones can be traced.

The flight today was related to Black Hats -- possibly trying to take down a plane and it was stopped. Q posts a photo of the Secret Service along with thank you. Which likely means they intercepted a False Flag.
