There is a significant flaw in this entire line of thought The P 51 is still being used to a greater extent today by air show pilots than it EVER was by the Dominican Republic Therefore it s 1957 or present If you argue against using 1957 then you must also argue against using 1984 unless as I said it s not an absolute date we re looking for The Confederate Air Force operates P 51 s on a regular basis as do several other private organizations and individuals Therefore there is going to be an astrics on ANY date we put in there it might as well be a significant date Therefore using your arbitrary logic I m going to put present on there and see if that flies
