It is entirely a military subject seeing as the military are the experts at deck oerations.
There are 4 Nylon lashings attached to the aircraft. But only 2 lashing numbers, so each guy has to remove 2 lashings. As the guy on the Port side moves aft, the Port Aft lashing comes off. The guy on the starboard side can't count or hasn't been briefed on how many lashings he has to remove as he only removes one (The Stbd Fwd one). His oppo who is busy trying to retrieve the wayward lashing on the Port side notices that his winger has failed to remove the Stbd Aft lashing and waves at it / him. Noticing his error he then rushes under the disc to recover it. At that precise moment and for reasons I cannot understand the aircraft lifts upwards and starts a forward transition.... The pilot clearly alarmed attempts to recover by hauling back on the cyclic only to dink the Tail rotor. So the aircraft is now about 5' above the deck with a lot of nose up and a TR failure.... Certain catastophe looming. However, by pure luck, the pilot dumps the collective and the aircraft lands onto the netting and comes to a stop. Meanwhile, Mr Forgetful on the Stbd side has taken cover and again by pure luck the aircrafts Tail rotor (now slowing down) misses his head by inches. Can't for the life of me understand why the aircraft lifted and transitioned forward, particularly when one of the lashings was still attached. The world experts at deck operations also attach 4 lashings but following an accident in the 1960's when an aircraft took off with a lashing attached and ended up in the mortar well we now always have one person per lashing. The 4 guys will walk under the disc together, remove their appropriate lashing and then walk out of the disc together. Once clear of the disc they then raise their particular lashing in the air whilst the aircrew count the number of lashings. Only when the aircrew have seen 4 lashings wil they start the take off process.....engaging the AFCS whilst on deck
