There is that lost'n'found box at the Hangar (on 1st floor). It contains an item. Try to take something from there.
How to get the item in lost'n'found
Henry would need to describe it to the cops. ( Talk to the cops about it )
But there ought to be other way... Talk to somebody else.
Talk to the cops about it
Talk to the pilot ( After talking to the cops about the lost'n'found stuff. )
