Thunder and Colt 90A envelope. 1991. G-BTPX 283 hours. Blue with white stars. Top Hyperlast panels in good condition. Bottom half ok and failed grab test at 9.5kg. Turning vents. No Scoop. Kevlar flying wires. Last flown July 2018 at European Balloon Festival. C of A revoked. Maybe a useful envelope for a “self build” for the wires and crown ring, etc. Training envelope, material for bean bags, tents, etc . All offers considered.
