Nervous flyers, look away now. A Vancouver flight was evacuated after an emergency landing at San Francisco International Airport on Sunday, March 1. The Air Canada Express plane had to turn around shortly after take-off from the Californian airport when a smoke alarm went off in a bathroom at the back of the aircraft.\nCTV News reported that 74 passengers and four crew members were on the plane, all of whom to be evacuated on the runway in San Francisco.\nJazz Aviation, which was operating the flight under the Air Canada Express brand, confirmed to Narcity in an email that the plane had to turn around after staff “received a rear lavatory smoke detector indication.”\nA spokesperson said the crew requested “priority landing” in San Francisco and that the aircraft landed safely.\nThe crew then had to perform an “emergency evacuation as a precautionary measure” and passengers were transported in buses to the terminal.\nHowever, when emergency vehicles inspected the plane on the runway, they found no fire.\nOne passenger spoke about the experience on Twitter on Sunday. He noted that their day had begun “with an emergency landing and jumping off the plane’s wing.”\nPassengers then faced a lengthy delay and landed in Vancouver around six hours after they were initially due.\nSo Saturday begins with an emergency landing and jumping off the plane's wing. #SFO #AirCanada pic.twitter.com/yrFY6L6eIm— Aman Dhillon (@DhillonJr) March 1, 2020\nMeanwhile, News 1130 spoke to a witness named Skip who works at San Francisco International Airport.\nHe described people “pouring out of the wings” at the front of the aircraft, claiming that one passenger had jumped off the plane, making an eight-foot drop.\nThe man also posted a picture and video of the situation on Twitter.\n@ClaudineKTVU pic.twitter.com/wK7O5ONBtF— skip Hovorka (@twuskip1) March 1, 2020\nEvacuation on Air Canada flight Sfo pic.twitter.com/OZu4DIERBN— skip Hovorka (@twuskip1) March 1, 2020\nThe incident happened just days after a Sunwing flight from Cancun, Mexico, to Calgary had to make an emergency landing in Memphis, Tennessee, after reports of smoke in the cabin.
