I've posted this before... but still interesting:
This happened to my attempt to push and Estes Generic E2X as hard as I possibly could...(D20-8). the tube split allowing the nose to collapse back into it. Obviously the ejection charge didn't get it pushed back out. Landed about 300ft away. It didn't get too high with all the extra drag from this on the front end....that's the only reason I was able to track it on a perfectly cloudless day with sun at a good angle. Had a reflective mylar "bird tape" streamer if it actually worked...
Obviously the inertia of accelerating the nosecone and recover harness, was more the radial capacity of the cardboard tube.

Going to try it again with a wrap of vinyl around the top inch or two of the tube for support. (I had a 12 pack of the Estes Generic E2X...)
Wow, I flew those on the old Aerotech Single use 18mm D motors; always a champ on those ; and many others I would declare on the launch card "Yet Another Disposable Rocket"
