Man forced off US flight for wearing thong as face mask
Adam Jenne, 38, was asked to leave the aircraft before it took off from Fort Lauderdale airport.
He told local news channel NBC2 that he wanted to show the "absurdity" of forcing passengers to wear masks on planes while allowing them to be removed to eat and drink on board.
Video of Wednesday's incident, filmed by another passenger, showed the crew informing Jenne that he would not be able to stay on board if he kept the thong on his face.
After some discussion, he finally left his seat.
Jenne said he had worn underwear on his face during previous flights, and told the air crew that "it is a mask, doing its job."
United Airlines said in a statement that "the customer clearly wasn't in compliance with the federal mask mandate and we appreciate that our team addressed the issue on the ground prior to takeoff, avoiding any potential disruptions on the air."
