Oh like 35 years ago my brother was a fly around mechanic on a DC-8 for the charter airline Capitol Airlines, and he would tell me story’s about 3rd world people stashing kids into the duffel bins and trying to start build their cooking fires on the floor of the cabin, so this is not surprising to me.
In about 1981, a Pakistan International Airways 747 was on its way from Karachi to Jeddah, carrying a planeload of pilgrims on their way to Mecca. One of the Paki passengers was right out of the hills, and when the flight attendants were busy elsewhere, this dufus fired up his portable stove to brew tea. Not surprisingly, a firestorm ensued. The pilots sat the plane down at Riyadh, but by that time the heat inside the craft was so intense that the the doors were welded to the frames and were impossible to open. The firefighters on the ground could only stand around and watch all the pax burn up. All aboard perished. The carcass of the 747 was left on the tarmac for some time.
