With 29 percent of its flights delayed, Ryanair has the worst on-time record, but one man found out Friday that the airline literally sucks.

After a piece of an engine broke off and shattered a window, the 61-year-old Serbian national in the window seat was sucked out up to his shoulders. His wife grabbed hold of his legs and held him there for five minutes to keep him inside the plane. He was observed to be bleeding and slipping in and out of consciousness, likely due to the lack of oxygen from the decompression caused by the gaping window.

Oxygen masks were deployed, and the airplane, which had only just taken off from an airport in Thessaloniki, Greece, 10 minutes earlier, heading toward Memmingen, Germany, returned safely to Greece, where the injured man was taken to a hospital for treatment.

Michalis Giannakos, president of the Panhellenic Federation of Public Hospital Employees, said he was being treated for friction burns, “is in shock, and remains conscious.”

Ryanair said in a statement that the flight returned “shortly after take-off when a passenger window dislodged in flight.”

“The aircraft landed normally and passengers returned to the terminal. One passenger requested and received medical assistance on the ground in Thessaloniki,” the airline said, adding that several hours later, “a replacement aircraft was arranged to bring passengers to Memmingen.”

The airline did not say what caused the incident, but passengers told local media that a piece of the engine had broken off and smashed into the window.

“We immediately realized there had been a decompression. There were screams … for a moment I thought someone had accidentally opened the emergency door,” said Christina, one of the passengers on the flight, in an interview with a local radio station.

“The masks dropped and there was a strong smell. The head and shoulders of one passenger were outside the window. Fortunately, he hadn’t taken off his seat belt,” she added.

“When the oxygen masks dropped, we had no idea what was going to happen,” Sofia, another passenger, told the radio station. “We didn’t know whether we would make it back. We were sitting at the back of the aircraft, and we realized there had been some kind of explosion.”

“We thought the plane was going down. The decompression was extreme. It felt like we couldn’t breathe,” she explained. “The man who was injured was bleeding and then lost consciousness several times, most likely because of the lack of oxygen and the shock.”
