Kids in cockpit.
One of the pilots had his family in J class.
Mexicana 940, 31 Mar 1986. Wiki has some info.
727 arrived MEX with dragging brake. Departing Capt boarded his family, headed for Disneyland.
This part I heard from people close to the event.
Rather than take a delay for brake or plane change the Capt, with a kid in his lap, used reversers to help the tug push the plane back from the gate.
MEX is at 7350 feet Elev. A full Mexicana 727 would typically rotate when abeam the red runway lights at the 12,000 foot mark of the 13,000 foot runway. Takeoff roll was on the order of 70 seconds. Initial climb was about 500 fpm until gear and TO flaps retracted.
NTSB reported that vaporizing/melting chemicals from the overheated tire combined with oxygen in the compressed air in the tire, and exploded.
Adding to the irony, it was reported that the Captain's wife, in a jumpseat, was a former Mexicana FA whose last prior flight was nearly destroyed by a bomb years before.
