At the same time a Jumbo was taking off from Paris heading for Boston. The two aircraft crossed when the 747 was 620 miles out of Paris. '02' was already 2,400 miles from Boston. This ranged from passengers to pilots to ground crew to aircraft engineers. There was the case back in 1998 when parts fell off a wing. The same aircraft, as it happened, but no harm was done and because of due diligence, it was never to be repeated.
People nevertheless remember and labels are made.
More latterly it has been said that spare parts were proving more and more difficult to find. Flight AF 4590, for instance, was held up for about an hour that afternoon due to Captain Marty's insistence that one of the four thrust reversers being replaced. They argued that these 'ol'Nellies' were becoming more trouble than they were worth. Secondly, Marty, a member of a very elite group of pilots, in pursuit of the Concorde's impeccable safety record, reasoned that he would be landing on a wet JFK airport runway with a heavy payload and he wanted all the breaking power he could use. Thirdly, to confirm the spares problem, a reverser was taken off another Concorde and put in its place.
