Dave, it wasn't a question of fogging the canopy, but of the entire cockpit being filled with fog. Take a close look at the Tab Z-13 picture and see how much fog is in the cockpit. If you notice, he has shed his visor in an attempt to gain some additional visability. That picture was taken after he was on the nosegear and under 140 kts groundspeed. The report states that both ships landed about 25 kts above calculated speeds. Aerobraking would have taken care of the excess speed, but when the AOA indexer and the HUD cues are no longer visable, you cannot maintain the proper aerobraking attitude. At that point you have to put the nose down and get on the nosewheel steering. As the report said, had the proper attitude been used, he would have stopped with more than 1000 feet of runway left, despite the excess landing speed. As to the speedbrakes, as the report states, it wouldn't have mattered that much. the speedbrakes are really used as a variable drag device and not used as a speed control device.
As to going around, about all I can say is that he most likely would have been getting a low fuel warning as he passed the end of the field and then the staff would have been dealing with an IFE call and possibly an ejection instead. No matter how you slice it, the pilot ws in a bad situation that could have turned out much worse.
