I was playing Destiny and something weird happened. I made a new character (my third, a Titan) and began on the first mission where the ghost revives you and you have to fight through the Fallen to get to the ship. I entered The Divide and got close to the point of entering the building you're supposed to go to and thought to open up the menu. Sure enough I saw that it said "SUMMON VEHICLE." I held down the X button and it summoned what I think is the basic sparrow. I looked in my inventory and there's a lock where the sparrow would go, and the scroll over text says "You do not yet have any vehicles to summon." I'm sure you're not supposed to be able to do this, and I'm not exactly sure what made it able to summon a sparrow at all.
