Well the hangar was brought up twice in the GDC talk, one where it was in the massive ship concept and then the final where it's in the tower in the last city. Personally I'd like to land my ship myself. It would be interesting if Bungie treated landings like they do on a Flat Top. From what I understand Navy pilots are rated on their carrier landings. I'd find it more realistic if you screwed up on too many landings, you'd get sent to a seedier air strip on the outskirts of the city till you proved you could actually land and not ram your ship into everyone else's rides. Or do you want a quick time event where you get close to the hangar and you get a auto pilot or cinematic?
