The DC-8 nationair crash was nothing to do with what the tyre was inflated with it was caused by underinflation coupled with a very long taxi in hot conditions, the tyre overheated and caused it to explode on retraction resulting in a massive fire in the wheel well, further cause was the inability of the saudi controller to understand the gravity of the situation, the aircraft made it to approach but the damage was so great due to the fire when the gear was extended the aerodynamic forces caused the tail to break off resulting in the crash. I actually visited the crash site, very tragic indeed but a lesson to us all.
