Victor 933

History
Victor 933 was a United Nations Space Command Pelican dropship attached to the in 2552. When the Autumn was shot down over Installation 04 that year, Victor 933 escaped intact, and was used by the Marines of Alpha Base. It appears however, that the Marines did not take any of the heavier UNSC weaponry, except for the shotguns that can be found on easy. It is found near the begining of the level 343 Guilty Spark.

It was sent out with Captain Jacob Keyes and Second Squad in hopes of finding a Covenant weapons cache. Twelve hours after the last transmission from the Pelican, the Master Chief dropped into the swamp aboard Echo 419 and found the wreckage of Victor 933. Apparently, the Pelican had been ambushed on takeoff and crashed into the swamp. One of the pilots managed to record and bradcast a last message, in case anyone found the dropship:

"Dropship Victor 93-(static)-the Pillar of Autumn-(static)-eed assistance. We are under att-(static)-attack by some kind of hostile-(static)-it isn't Covenant. (Static) Captain Keyes has been captured by hostiles. (static)-dug in at a large structure in a swampy area. We need to pull out. Please-(static)-I will set this message to repeat at-(static)-given interval. Dropship Victor 933, clear."

The recording is loudest in the back of the passenger bay, by the cockpit. The door leading to the cockpit is closed however, and the message is likely a short-range radio-transmission.

The vessel was shot down by the Flood with repurposed heavy weapons, with the recording saying: "attack by some kind of hostile -(static)-It isn't Covenant.

Trivia

 * In later missions, such as the Silent Cartographer, the body used for Victor 933 is actually the second Pelican which drops off Marine troops. You can see the label V-933 on the side haunch of the dropship. And after you discover the location of the map room and you go out of the structure, you see a pelican downed (the one who brings in a warthog and some rocket launchers), if you see the label on its side, it actually says V933.
