I recall India lost a few officers in a plane crash while carrying out geological surveys as a part of uranium prospecting.

I could not convince my colleagues about the need for incorporating unpleasant pictures of radiation burns in training material for radiographers.One of their arguments was that public may misunderstand it.

Hi Dr. P:

I remember taking my helicopter safety training years ago for geological reconnaissance in remote areas. The entire training took 1 week. Part of that training involved watching & discussing films in which very badly burned pilots were reporting on their personal experiences of survival following catastrophic failure of aircraft. Following that training, I spent several weeks involved in "higher-hazard" flight operations at high altitudes.  I had one very close call after a main rotor stall 3 meters above the ground at about 3,300 m elevation. The helicopter became a very large "weed-eater" for a few seconds and the rotors barely managed to miss several large boulders. I was wearing all my safety equipment (nomex flight suit, gloves and helmet). The company that I worked for lost 2 crews and helicopters doing similar work over a 2-year period.  One of these crashes resulted from a rear-rotor failure.  The other was likely due to a main rotor stall
 while attempting to land at high altitude, similar to my experience.

Personally, I feel that such graphic means are necessary to impress on personnel the potential dangers inherent in these sorts of activities, but re-training is required. Perhaps if the individuals involved had an occasional adrenalin rush from a "close call" (such as in other hazardous work), they would be more respectful of the danger potential.

Training for normal operations is not difficult; knowing that if part of the equipment fails, it's time to go to your supervisor or company of manufacture and get advise that may not be in the operations book is essential.  I think the equipment failure as described would be the helicopter equivalent of a main rotor stall or worse... And that is an unthinkable failure.

I remember this exact sort of failure occurred on geophysical logging trucks from time to time.
