It is an excellent report. I'm a bit concerned with the conclusion that the ASH 26 glide ratio decreased from 40:1 to 10:1 with the mast extended. I have not experience that severe of a decline in L/D in the 18m config on my ASH 31. I would surmise that he experienced sink on the approach to the airport that wasn't noted. Why he didn't just "slam" the mast down ASAP after he couldn't start the engine would be my first question to the pilot.

Indeed.
My flight manual (different model) encourages even partial retraction,
but trying that gets busy in cockpit.
Report does confuse L/D with actual recorded glide angle...
