You're right. From #1:
The two National Guard pilots in their nearby helicopter now picked up the streaks high in the sky. Capt. Chris Baur saw the streak Brumley had first observed: "Almost due south, there was a hard white light, like burning pyrotechnics, in level flight. I was trying to figure out what it was. It was the wrong color for flares. It struck an object coming from the right and made it explode."
Maj. Fritz Meyer, a winner of the Distinguished Flying Cross for his service over Vietnam, saw the southbound projectile clearest. "It was definitely a rocket motor," says Meyer.
I know you've seen this before, but just to refresh your memory: From the Grenada Forum, ANG Pavehawk helicopter pilot Fred "Fritz" Meyer says...
"When you fly a helicopter at 120 knots over North Vietnam in the iron triangle - in the most heavily defended airspace in the history of warfare - you see a lot of missiles - you see a lot of flak - and I did - I saw a bunch of it - I know what it looks like. My purpose in being here tonight is to tell you that what I saw explode in the sky on July 17, 1996 was military ordnance...We're here is to say it's no accident - somebody shot this aircraft down"
