Authorities said they had to wait until a search beneath the F/A-18's wreckage was complete before they could say with certainty no one was killed in the Friday crash, CNN reported.
The plane suffered "catastrophic mechanical malfunction" during takeoff and dumped fuel before the fiery crash damaged five apartment buildings, Navy officials said.
The leaking fuel was "one of the indications that there was a mechanical malfunction," Navy Capt. Mark Weisgerber told reporters.
The plane may have dumped fuel to minimize the fire upon crashing, CNN said.
Both pilots ejected from the plane, the Navy said.
Seven people, including the two pilots, were treated for injuries at Sentara Virginia Beach General Hospital.
A pilot was in good condition at the hospital Saturday, CNN said.
The jet was part of a training squadron at the Naval Air Station Oceana, the Navy and the Federal Aviation Administration said. The plane wasn't carry live ordnance. A Defense Department official said it crashed 2.2 miles from the runway.
Pat Kavanaugh, a resident, told a CNN affiliate he and others found one of the pilots still strapped to his seat with cuts on his face.
Weisgerber said the crash is under investigation.
About two dozen residents were staying in a temporary shelter.
