A technical question for those that might know -- refresh my aging memory -- isn't the Zuni motor the same as that used on the Sidewinder...? Originally, I'm pretty sure Sidewinder was designed using Zuni bodies and motors. Nope. The Zuni burn time was very short, perhaps 1 second. SW was at least 5. I've fired both from fuselage pylons on the F-8. The Zuni approximated a freight train speeding past your head with about 6 inches clearance. IIRC, the Mk 17 motor on an early Sidewinder burned for about 2-2 1/4 seconds. The Mk 36 in the AIM-9C and its derivatives burned for something between 4 & 5 seconds. The Mk 36 has more impule (Total energy), but lower thrust. -- Pete Stickney A strong conviction that something must be done is the parent of many bad measures. -- Daniel Webster

I know I've got it, but can't find the data -- Aargh! Guy
