Came across a documentary on yewchoob the other day on Tornado Down which included interviews with the crew. I was interested to hear John Peters say that he 'popped out his contact lenses' not long after landing in his 'chute. Which made me think;
1. I didn't think FJ crew could wear contacts lenses? I thought there was a 'g' issue with them? Not to mention them potentially moving about when flying.
2. If you happened to be 'downed aircrew', glasses or contacts are not going to be with you for long so you will have to manage without 'in captivity'. Given what happened to these guys, probably not a big issue but could be if you were planning an escape.
