“We’re out of time.” Those may be some of the last words heard from the cockpit of the private jet that plunged into a Florida neighborhood Sunday. Audio circulating online appears to capture the pilots of the Learjet 60 talking with air traffic control before the crash in Greenacres, Palm Beach County. The FAA says nine people were on board, flying from Austin, Texas, to the Bahamas. Instead of a vacation, the jet dropped from cruising altitude almost straight down and exploded into a mobile home park just before 1 p.m. Reports say none of the nine survived. Nine families woke up expecting a trip to paradise, and tonight they’re getting the worst call of their lives. The NTSB is now trying to figure out what went so wrong, so fast. What do you think could cause a jet to fall out of the sky that quickly?
