Yeah obviously they did not teleport to that spot. And indeed one seems to be a crewmember. So when it is related to the F1, I guess they just climbed up for a better view.
Just at their feet, is an open hatch, presumable there is a little ladder there and a hatch to get up there, I can imagine that they might need to get up there sometimes anyway, for maintenance, or when there's a problem..
But maybe there's a ladder on the outside somewhere aswell, because that one bloke, well.. it seems he would have a bit of a hard time getting through that little hatch.
