A passenger on a plane travelling from London to the US threatened to kill flight attendants and blow up the aircraft, it has emerged.
The FBI said Kevin Mosele, 20, of Kihei, Hawaii, was charged on Tuesday with interfering with a flight crew and could receive 20 years in prison if convicted.
According to the criminal complaint, Mosele told investigators he had several drinks in London before boarding the plane.
On the plane he became agitated, spitting water at the crew and saying he would kill them, then saying he was "going to set off a bomb".
The FBI said he had to be restrained and was arrested when the plane landed on Monday for a stopover in Los Angeles. It had been headed to Hawaii.
Mosele is free on 10,000 dollars' (£5,800) bail.
