Thought I had seen something about an airlaunched ballistic missle, one was the Skybolt the other was a Minuteman I dropped from the rear of a C-5A Galaxy, then ignited (description about halfway down Wikipedia article)
Thanks guys, but as has been noted, that is a Minuteman I. This is the Skybolt:
The tail cone gets blasted off by the motor igniting after the thing dropped from the carrier airplane.
I made a semi-scale LPR version because I had a WAC Corporal nose cone that the tip broke off of. I sanded the broken end round and voila; Skybolt nose! I always thought the Skybolt was a neat looking thing and building the little one made me want to do a bigger (MPR), true scale version.
If you run across any info I would appreciate seeing it!
BTW - The video of the Minuteman aerial launch from the C-5 is pretty spectacular. If I can find it again I'll post it here.
