New York (CNN) -- Cellphone video captured by two New York-bound Delta Air Lines passengers Saturday night portrays the fear of an impending crash and the relief that followed when the pilot averted a catastrophic landing.
"Brace for impact," a deep voice says on the intercom.
"Heads down! Stay down! Heads down! Stay down!" a woman commands for more than 30 seconds.
Two passengers aboard Flight 4951 from Atlanta, Georgia, to White Plains, New York, taped the dramatic moments of their flight's emergency landing at John F. Kennedy International Airport in New York.
The passengers who shot the footage, Chase Benzenberg and Alessandro Albero, said Monday on CNN's "American Morning" that what first seemed amusing soon turned into a serious situation.
"While we were circling Westchester Airport, we circled for a good 20 minutes and we were joking around with each other, saying, 'I don't know if he knows where the landing strip is,' and then they made the announcement on the loudspeaker,"Albero said.
