Yes, I wondered the same thing too. Also you could clearly see dozens of access panels inside the rotor assembly that had already been partially removed by someone before, who obviously came in from above to salvage some things. As to the seat removal to be done later, IMO that didn't really need some fancy precision pincer-biter-thing to accomplish, though they may have needed it for other reasons anyway.
But Just why? Im shure that much People like to pay to have ride in that amazing machine. Why is tunel under canal must spoil every thing? Maybe that hover can serve in some other place?
