Delta passengers and crew are forced to subdue off-duty flight attendant who seized the intercom and ‘vowed to bring jet down’

An off-duty Delta flight attendant was subdued by his colleagues and is in FBI custody after saying he wanted to take a plane down.

The man, whose identity was not revealed, was on Delta Flight 1730 from Los Angeles to Atlanta when he allegedly took over the intercom before assaulting two flight attendants, CNN reported. 

He is said to have told passengers that oxygen masks would drop from the ceiling, leaving some fearing the jet was on the verge of crashing.
