Victor 398

Victor 398 was a UNSC Pelican dropship that crashed into the mountain gorge that is the Halo 3 multiplayer level, Valhalla.

Background
The crash, which the crew barely survived, also scattered the Pelican's contents throughout the valley. V-398's rear hatch is sealed, presumably by the surviving crew members, which denies access to the aircraft's interior. It was most likely on an ammunition run, due to the several Type C Resupply Capsules scattered throughout the area.

It is unknown how the Pelican went down, though it is a possibility that the Forerunner Beam Emitters atop the "bases" in Valhalla may have accidentally hit the Pelican, but this is unlikely, because for the Pelican to come to rest in it's current position it would have had to come down on a path that does not pass over them. Due to Valhalla's location on the Ark, it is more likely that V-398 was shot down during the Battle of the Ark.

Trivia

 * Victor 398's crash position is the same as Victor 933 (possibly the same model, but with high quality graphics), and may be a nod to the earlier game.
 * In the popular machinima series Red vs. Blue, this is the ship Tex crash lands in.
