These people died because the autopilot was flying them and the vacuum pump it was linked to failed - with the terrain and the height they were at they had little time to notice something which has killed a lot of current IR pilots.
There is nothing red top about telling the truth.
Don't blame the vac pump. They took off in to non VFR conditions without the neccesary training and qualifications to cope with the problems that could arise.
No doubt they had employed the same trick in the past but this time fate took a hand.Play with fire and at some time you will get burnt.
I just hope others who fly will the same attitude will think again after reading the AAIB report and the details of the inquest.
