I think the talk about runway lengths, IFR into VFR is off the mark.
The case where an aircraft can impact reletively flat ground with the engines at flight idle, speedbrakes out etc indicates very poor situational awarenes. Who was watching the shop when they went below the MDA. Even the most inexperianced night VFR student has this hammered into them. Monitor distance, altitude and flight path.
Btw, 1400m shouldnt be a problem for a C750. They put 737-800s into snow covered runways that are 1500m long at Midway.
