I rather enjoyed the Radio 4 interview with Nick Patrick who has done 18hrs of spacewalking some 10 years ago. The Radio 4 presenter asked him what it would be like for Tim to do a spacewalk.
BBC Radio 4 - Today, 15/01/2016, An astronaut's guide to spacewalking
I probably need to remind the teeny-brained Teeny Weeny Airways chaps about Nick. He is British born, the RAF taught him to fly, he attended Harrow/Cambridge, carried a RAF Ensign into space for the Chief of the Air Staff and in the clip you can hear he has still got a fine English accent. He had to become a US citizen to get his way onto the NASA program and flew in a spacecraft with wings rather than a washing-machine tub with a heat shield.
Read it and weep Teeny Weeny boys, your ex AAC chap got there after the ex RAF chap...
