02/23/2004. Remarks by Scott Hegland: "The photo above and this one showing the in-air refueling between a B-66 and a KB-50, were taken by a (then) Captain Stamm who indicated that along with this likely being one of the actual aircraft that my dad flew. He also mentioned that this particular aircraft was 'the only B-66 that I know of that was shot down by a Mig 21 in the Vietnam conflict'. He went on to say that 'perhaps if the guns had been left on that wouldn't have happened. But, long before that war, a chaff dispensing tailcone replaced two 0.787 in (20 mm) guns on all 66s."
