Pilot magazine commented on it years ago (but still years after the event) - the canopy iced up entirely, so when the world's highest altitude (without payload) became the world's highest autorotation, Boulet was reduced to using the position of the dimly-seen sun through the layer of ice as a horizon reference. He thought things could only improve after it got in line with the floor. Luckily they did.
And edited to say one of the things they stripped out for lightness was the electrical system, which made a restart impossible regardless of the fuel state.
