Some pic info
Cupola is Mick Eth role equip. Dad directional consultant.
Desert landing trials were in Uk. DvHelmut bent ac in theatre on take off. BofI found he had done everything correctly but no factors given in ODM for sand or gravel. Initial data done at Pendine then a couple of good days on Saunton Sands. (Got pics of that as well, professional photog local paper) Couldn't find gravel strip in UK so, reluctantly, had to spend some time in Spain.
