I received this rocket kit on my 10th birthday back 1977.i had q neighbor build it for me over the course of a week and a half.i was so exited to launch this rocket .I had a scout and this was a huge jump up from that.we launched in late April with a C-65 and it was awsome !!!that launch was so fast and it went so high I could barely see it then the arch and it popped its chute. Thing is it was way way way to high to pop its chute and the jet stream took my brand new first time launched rocket to Mexico. I was so sad I had to scratch it of my life list 48 years later.i was shocked to see that it was still available and I'm kinda thinking I would like one of those 3 foot ones.but the interceptor gonna hang from the ceiling of my room like it was supposed to back when I turned 10.
