So I'm having a very annoying problem: Paladin Danse won't give me the next Brotherhood of Steel quest (the one that has me go to the prydwen, via vertibird), and he won't have cognitive conversation, just a repetitive menial response, including "I'm busy right now." I've done Haylen and Rhys's missions for 2 and a half hours. Can someone help me?
Progress with the main story quest to get ahead with the Brotherhood of Steel. Before that, you can only repeat Rhys' and Haylen's quests over and over.
[Possible Spoiler] When does the next quest appear?
Near the end of the quest Reunions (credit to DCShannon)
