I've said it before and I'll probably say it again...
Some years ago, a facsimile edition of the flying log books of RR Stanford-Tuck was produced and I believe, sold out fairly quickly. If someone were to do the same with the log books of Captain Brown, I would pay a tidy sum for a copy. On the recent Desert Island Discs programme I think he mentioned there were 11 or maybe 12 log books detailing his flying!
