I believe the "solo suicide mission" that gulliBell is referring to is the roll-over of a 222 while an engineer was performing a maintenance ground-run. Although the helicopter was destroyed and the bulk-fuel installation badly damaged, the engineer and mechanic were only slightly shaken. At that time, East Asia Airlines was one of the few "progressive" operators that permitted trained and certified senior engineers to perform maintenance ground-runs on their helicopters (up to 100% Nr, flat pitch only). This company approval meant that maintenance personnel didn't have to sit around waiting for a pilot to show-up for a ground-run and that pilots didn't have to wait around at the end of their shift until, for example, the engines cooled sufficiently for a compressor wash to be accomplished. Essentially it was a win-win situation for both parties. Apologies for thread drift.
