If it is true that the Captain did not request main wing deicing it was an inexcusable mistake, especially in the darkness - the preflight should include physically touching the wing upper surface for snow, ice or frost as any beginning pilot learns. Due to its wing design, the F-100's normal takeoff calls for clean 0 flaps unless there is a need to climb to altitude more rapidly - and, yes, there are no leading edge slats. There have been other notable Fokker accidents nearly identical to this one, however, and the model aircraft and manufacturer failed.
