Bugs
It's possible that when you are getting in the vertibird you stop at the Airport not at the Mass fusion OR, and when you go back to the Prydwen you can't enter at the vertibird anymore, reload at a save before leaving the inside of the Prydwen may fix the problem.

There is a bug when you jump off the vertibird to the rooftop. The quest does not advance and still tells you to jump off the vertibird.

It is also possible that when on the vertibird, the game will crash while trying to fight the synths on top of the first tower
