I had the pleasure of working on the HH-60D Nighthawk at the 6515th TSS. It was a test plane developed in the early to mid 80's and only flown at Edwards AFB. The patch was reworked as it looked like it said HH-GOD. It was also scrapped @1987. The picture shown is not a HH-60D 09/16/2007 @ 05:33 [ref: 17936]
