Thanks to Bill Schneider from the Khâm Đức Group, who added the following comment: the aircraft was guided off the runway on purpose by superior flying skills. It did not catch on fire at that time but was destroyed for good by USAF fighters that destroyed all remaining assets on the ground, including the SF Camp, engineer equipment and anything that could be of any value to the North Vietnam Army. Delmore's crew was picked up just a few minutes later by a USMC CH-46 helicopter.
