An investigation is underway after a passenger with no flying experience safely landed a plane after the pilot fell ill.
The remarkable incident is believed to be the first of its kind in history.
It involved a small 14-seater plane, which was flown by the brave passenger for around 100km to safely land at Palm Beach International Airport in Florida, US on Tuesday.
The terrifying incident happened when the pilot fell ill, Mirror UK reports.
The quick-thinking passenger called Air Traffic Controllers to tell them the pilot "has gone incoherent". They were able to help guide the man to land the Cessna Caravan plane safely.
The passenger - who has not been identified - was told to keep the wings level and follow the coast before he was coached to the ground during the nail-biting ordeal.
"I’ve got a serious situation here,” the passenger was heard saying over the radio.
“My pilot has gone incoherent. I have no idea how to fly the airplane.”
Controllers asked for his position and he said he had "no idea" but that he could see the Florida coast in front of him.
He was told to follow the coast while they tried to locate the plane, which they spotted around 40km from Palm Beach.
Following the successful landing, a controller is reported to have said: "You just witnessed a couple passengers land that plane."
“Oh, my gosh. Great job,” said the other person.
Aviation expert John Nance told WPBF-TV the dispatcher's praise was actually a huge understatement.
He said: “This is the first time I’ve ever heard of one of these [Cessna Caravans] being landed by somebody that has no aeronautical experience.
"The person on the airplane who had no aeronautical experience listened very carefully and obviously followed instructions with great calm.
"That’s what made the difference," he added.
The Federal Aviation Administration continues to investigate what happened to the pilot.
