Danny, post 9360 at the bottom of page 638 should give some answers. If only John were still with us... He would have been thrilled at the response and somewhat embarrassed - we could have gone into the fine detail. The next post should shed some light - please don't get fixated on casualty evacuation! I will try and find out where his son is and see if he has John's log book. That should give us some answers. When we get to Five into four won't go, I have a page of his log book to illustrate the story
