Okay, with the confirmation that my guesses for the first three teams were correct, we only have one pair and the trio to figure out. We also know from Ace's comment that he's part of the pair.
I'm going to take Space's comment that I was "close" on my guess that
@Outbound is on Team 5 to mean that similar logic was used for the clue, if I wasn't outright correct on that front. As such, I am guessing that this is
@AceAstro's team, as a play on the term "Ace Pilot." If Outbound is not on this team, then my second guess is
@JokersWild, since it specifically uses a pic from a rather "Jokey" version of airplane disaster movies.
This leave the remaining three (
@PerGron,
@mickeyfan5534, and either
@Outbound or
@JokersWild) for Team 4.
