Another awesome episode. Mack hammer! Hahah Coulson's line you can't touch this.... Classic hahaha. It's pretty cool that Deek has found out that Fitz and Simmons are his grandparents I wonder if he'll tell them.

Yeah, I liked the oldies references too.

But seriously, what are the odds that what appeared to be an Arleigh Burke class destroyer could have floated at 25K ft for god knows how long undetected? Hell, you would think it would have been picked up on radar used for aircraft collision avoidance almost instantly.

Commercial planes fly at a higher altitude around 39k feet. Longer flights fly even higher. If it was far enough out planes could easily be at their cruising altitude and wouldn't see it.

Visually, no, but what about radar? Air traffic control radar, or perhaps military defense radar should have certainly picked it up.
