An infinite loop model would certainly qualify as long as it demonstrated a qualified glide. I recall reading years ago that a Centuri Groove Tube model settled into a stable gliding return after the shock cord had broken. The nose cone descended with the parachute while the booster glided back seperately.

Same with my first Centuri ScramJet clone. The nose cone floated off over toward the Ohio River while the body made a big, looping return to the field. We were up quite high, so we were able to see that nose cone and parachute for a while.
