Nobody is denying that the "Kiel Canal" incident was anything less than a horrendous clusterfeck which resulted in avoidable injuries and loss of life. Lessons were learned and further safety measures incorporated in main force para assault exercises. The reports from Bold Guard remained on file at JATE for years.
The OP however relates to Special Forces procedures which are entirely different to those employed on main force drops. The article itself is disingenuous and misleading being 5 years old. There are no K model C130s left. With deepest respect to the survivors of the '74 exercise I can see no point to answer in this thread.
