Fascinating, was looking at the Mew Gull in the hangar at Breighton recently and was wondering how he managed to navigate then land the thing at the sort of strips mentioned in the book - no forward vision and not much to the sides either! Time and again he is unsure of his position having dead-reckoned his position over hundreds of miles with no fixes, then manages to spot a strip at night or in fog in the middle of nowhere.
Glad to see someone attempting the record but with modern avionics it will be so much easier. Still a challenge but takes nothing away from Alex Henshaw's feat.
