That's because I'm putting them in this post. /ok
As you can plainly see, here I am approaching a CIS hangar in third-person view, flying relatively high in an attempt to provide clearance for the downward-facing wings.
But it doesn't quite work out as planned. As you can tell from the debris, the V-19's object collision area was actually lined up with the ceiling of the hangar, not the middle, as our visual perception would have us believe.
In this attempt, I switch to first-person view by hitting the V button, and angle myself so that I'll fly directly into the hangar.
Lo and behold, I make it inside, and the only thing I'm in danger of crashing into are the waiting ships. Which I did, several times, almost killing me. But I didn't. Behold my leet piloting. Anyway, moving on.
And now we return to third-person view to discover that the down-sweeping wings, which obviously have no object collision properties, are poking through the floor of the hangar.
The lesson of all this is as follows: When attempting to land, treat the V-19 as though it doesn't have down-sweeping wings, and you'll do just fine.
