Flames
A Redditor’s mother was on a flight from Belfast to Birmingham and looked out of the window mid-flight only to see that the engine was on fire! She calls the stewardess, who says she’ll tell the pilot.
The pilot reassures everyone on the plane that the fire they see is only excess fuel burning up. To this day, their mother has no idea if they were telling the truth or not. But she said that she doesn’t ever want to know.
