A passenger aboard United Airlines Flight 1871 captured a video that appeared to show flames leaping from the plane's right engine a few minutes after the flight took off from Newark Liberty International Airport Wednesday night.
United Airlines officials said the jet suffered a mechanical issue and was forced to return to Newark.
"I didn’t know what was happening," passenger Gabrielle Guzy told ABC News. "My sister said she thought it was lights, but I knew it was fire from the engine. I kept reassuring myself we’d be OK because we had only been in the air for a minute."
United representatives said the plane landed safely and passengers deplaned normally.
