Understand the record was in a Lama, stripped and prepped for the record flight. The pilot was the lead Aerospatiale test pilot, they flight if I remember was done in Chile, the calculated the fuel to reach 40,000 feet and off he went, I think he actually reached 41,000 before be ran out of fuel, then he autoed for 40 minutes most of it IMC and with the inside of the bubble iced up since they had removed the heater. Eurocopter should have the details of the flight.
