Yes it was a pattern made craft and in some kind of miracle there was no fireball.

“The Galloping Ghost is one of nine hundred P-51-15-NA type Mustangs produced by NAA during World War II. It was originally delivered to the Army Air Forces (AAF) on 23 December 1944 and later was assigned to the Third Air Force before being declared surplus on 25 October 1945 and put in storage at Walnut Ridge, Arkansas.”
There was no fireball because of good engineering and limited fuel on board.
