It’s not funny, people.

That’s the message the Indonesian authorities are trying to send, as a sudden rash of jokes about bombs has resulted in flight disruptions across the country.

On Monday night, at least 10 passengers suffered injuries, including broken bones, after a 26-year-old man on a Lion Air plane preparing to take off from the city of Pontianak on Borneo island told a flight attendant there was a bomb on board, The Associated Press reported.

A video circulating on social media appeared to show what happened next: passengers on the wing, fleeing the plane. The A.P. quoted an airline spokesman, Danang Mandala, as saying that a panicked passenger had opened both emergency exits on the plane’s right side without the cabin crew’s permission. The police later searched the plane but found nothing suspicious.
