During a recent flight out of Las Vegas, a Southwest Airlines captain became "incapacitated" and "needed medical attention" soon after take off.

Luckily (for all the passengers and crew), an off-duty pilot from another airline was onboard.

The off-duty pilot jumped in to help turn the plane around and safely land back in Vegas.

From CNN:

The incident began not long after Flight 6013 to Columbus, Ohio, took off from Las Vegas Wednesday, Southwest Airlines said. One of the pilots "needed medical attention," the airline said.

"A credentialed Pilot from another airline, who was on board, entered the Flight Deck and assisted with radio communication while our Southwest Pilot flew the aircraft," said airline spokesperson Chris Perry. "We greatly appreciate their support and assistance."

The airline said a nurse on board cared for the pilot, but they did not release any details on his condition or health issues.

Apparently, someone was heard saying the pilot was experiencing stomach pain and "fainted," according to NBC News.

A flight crew member was heard telling air traffic control that the captain "became incapacitated while en route."

He's in the back of the aircraft right now with a flight attendant, but we need to get him on an ambulance immediately.

Flight 6013 was in the air for about 1 hour and 17 minutes before landing back in Vegas. A backup crew boarded, and the flight continued to Columbus as initially planned.

Talk about a close call! 😰

The Federal Aviation Administration will be investigating the incident, it said.
