Would the aircraft do the entire transit from Lossie to Nellis non stop? It must be the best part of 12 hours with the Pilots in one position, DVT, Liquids, food and all that!
My best was 10.15 one way and 10.35 back the other the next day in an F3 during GW1, don't know about DVT but it was a pain in the arse.
