It was one of my group from BEA on his first line trip as I was..at the time I was way on the backside of the learning curve as although 6 years on the gripper command decisions weren’t up to me. Chris who was PF went to divert around a rocket cumulus..it was explained to me 25 years later by the BGA national coach which is when a small cumulus goes ballistic and looks like the cloud left by a Saturn rocket launch..absolutely no use for gliders as short lived. The line flying instructor decided that PF was being a big girls blouse and steered through it which left around 10 pax being taken to hospital having damaged the ceiling as well as a seat or two when they came back down. IIRC bergerie and I were scheduled to continue to Mauritius but went a day or two later to Hong Kong via a close encounter with an Air India 747 over the Bay of Bengal.
