Welcome back to our channel for a feature on the newly updated USMC heavy lift helicopter, the CH-53K King Stallion, from a design dating back to the 1960's, this amazing aircraft will see service for many more decades. One of these, straight from the production line and readied for its initial flight test, inverted at around 300 feet, crashed and burned. New aircraft and newly worked on aircraft are particularly dangerous, as has been proven throught history. Engine failures in single engined carrier aircraft that had just been worked on was not uncommon, though the actual causes could not be determined because the aircraft crashed into the sea and sank beyond recovery (after the crews ejected). These helicopters are particularly complicated, maintenance hungry beasts, and despite the best intentions and work inspections and sign offs, problems occur. As an ex RAF tech it always amused me how many people are needed for one jet or helicopter in the USAF! We do everything on our own but the yanks have, literally a guy for each task.
