That is so tragic and my condolences go out to the family, such a waste, I myself witnessed similar in the RAF when the nose doors closed on an electrician working on a Jag that had returned, I was seated in the next jet working on it and saw him lifted off the ground, luckily on the Jag the gear doors could apparently be sequenced the other way without the need to complete the full cycle, I remember it like it was yesterday, he got away with some broken ribs.
