Here’s a look at the Winter Soldier and Captain America minifigures. Unfortunately, neither one of them is exclusive to this set, with this version of Winter Soldier making an appearance in 76047 Black Panther Pursuit. Captain America has been a lot more promiscuous, having made an appearance in 2 sets (Quinjet City Chase & Hydra Fortress Smash) and a polybag as well. His torso is also identical to the one from Black Panther Pursuit.
A minifigure can comfortably fit seated inside the cockpit, and it is here that I found the first issue with the set. I had no issue inserting and removing the figure from his seated position, but my seven-year old struggled to get him out, deciding to leave him onboard instead of disembarking after she brought the jet back into the hangar. The physical connection between LEGO pieces in the cockpit and the pilot minifigure didn’t seem to present an issue, so whether or not this was just a one-off issue remains to be seen.
