Me thinks Rainboe talks a lot of horse manure
Some of his facts are pretty close to reality, but the vast majority is way of the mark!
I'm not sure what qualifies Rainboe as a 'fountain of knowledge' in all departments, and I certainly wouldn't quote/repeat anything he writes. If you are SLF and interested in aviation there are plenty of books and internet sites dedicated to this sort of thing - which I can assure you will be a whole lot more factual than his ramblings!
