Officials say they still have not accounted for all the residents who live in an apartment complex where a fighter jet crashed, leveling several buildings.

Capt. Mark Weisgerber is with Fleet Forces Command. He said Friday that a student and instructor were on board the jet when it crashed in Virginia. Both men are expected to survive.

Some 40 apartment units were damaged or destroyed by the crash in Virginia Beach. Seven people, including the two pilots, were treated at hospitals and were expected to survive.

Weisgerber also says that while the jet dumped loads of fuel, avoiding what could have been a large explosion, it's not clear if that fuel dump was intentional. It's possible the fuel was dumped because of a malfunction on the plane.
