My geuss is the F-16 pilots figured instead of landing on the numbers, they would touch down further down the runway so the crowd would get a better view of touchdown . I see no mechanical failure . All that weight on the nosewheel during hard braking on soft ground it just ripped the nosewheel right off .
I see no photographic evidence supporting your assertion that the nose gear "just ripped off". In every photo posted thus far, there is NO visible shedding of nose gear parts, tires, wheels or structure. There is NO detectible deformation of the nose gear strut/cylinder from its essentially vertical orientation with a slight forward canted angle.
Without raising the aircraft, I would interpret the photos as indicating that the nose gear is simply BURIED in the soft turf soil, without significant structural damage but probably having sustained substantial abrasive damage.
The typical fighter aircraft landing gear is structurally engineered to survive extraordinarly abuse in hard landings and a high life-cycle rate.
IMHO
[edit: Added the following...]
The "plow effect" of the nose gear would also explain the large amount of displaced soil seen "airborne" forward of any other potentially disturbing influences, such as the Main Gear or any air turbulance.
Even the Nose Gear Door seems to remain in its proper position, further supporoting this "Soft Soil" theory.
