DENVER — A fire on an American Airlines plane after it diverted mid-flight and landed at Denver International Airport sent passengers fleeing onto a wing in a fraught evacuation amid billowing clouds of smoke. Airport officials said 12 people were taken to hospitals with minor injuries.

The country has seen a recent spate of aviation disasters and close calls stoking fears about air travel, though flying remains a very safe mode of transport. Recent on-the-ground incidents have included a plane that crashed and flipped over upon landing in Toronto and a Japan Airlines plane that clipped a parked Delta plane while it was taxiing at the Seattle airport.

In this latest incident, Flight 1006 was headed from the Colorado Springs Airport to Dallas Fort Worth on Thursday, but diverted to Denver and landed safely around 5:15 p.m. after the crew reported engine vibrations, the Federal Aviation Administration said in a statement. While taxiing to the gate, an engine on the Boeing 737-800 caught fire, the FAA added.

Photos and videos posted by news outlets showed passengers exiting the plane onto its left wing as an engine on the right wing burned and black smoke surrounded the aircraft. They lined up and got to the ground using slides and ladders brought over by groundcrews, according to the FAA, videos and passenger interviews.

American said in a statement that the flight experienced an engine-related issue after taxiing to the gate. There was no immediate clarification on exactly when the plane caught fire.

All 172 passengers and six crew members were safely evacuated from the plane, authorities and airport officials said. American Airlines referred questions about the 12 people taken to hospitals to local officials. Ten people were taken to the University of Colorado Hospital in Aurora but spokesperson Kelli Christensen said she did not have an update on how many were there Friday.

A replacement plane and crew took passengers to Dallas-Fort Worth, the airline said. The flight landed Friday around 5 a.m. local time, according to the flight-tracking website FlightAware.

As the Wolves got healthier the past few weeks, the fan base asked questions like, “What’s going to happen when Randle comes back?” Then it was, “What’s going to happen when Gobert gets back?” The early returns have been nothing but positive as the Wolves enter the home stretch of the season in a race to avoid the play-in tournament.

“We got a gift earlier in the year with some of the injuries, myself included, being injured a little bit, guys being in and out of the lineups, it’s given other guys opportunities to have a bigger role,” said Conley, who had eight points and five assists. “You look at Jaden and Naz [Reid], those guys are getting comfortable and confident while Julius was out.

“Donte, him being out allowed Jaylen [Clark], T.J. [Terrence Shannon Jr.] and other guys to get quality minutes. Now we’re all finding our rhythm. We’re all finding a good pace to the game.”

Now to keep up this pace the rest of the season, and when the opponent isn’t Denver.

“When we play, part of our issue is bringing the same focus and intensity level and commitment to the game, no matter who we’re playing,” Finch said. “When we play these top teams and teams we have great familiarity with, we tend to take it a bit more personal. We have to do that all of the time.”
