Endeavor Air flight 3925 was scheduled to leave LaGuardia airport in New York City at 11:30 a.m. on Monday, but just prior to boarding, a heated argument broke out between a 54-year-old male pilot and a 26-year-old female flight attendant, reports The New York Daily News.
A source for the Daily News claims to have overheard the altercation, but did not clarify what caused why the pilot and flight attendant were arguing in the first place.
