...actually overflew central Amsterdam two times as it was postioned for an approach to RW27
The first time though, was during the (uneventful) climb-out, before engines 3 & 4 fell off.
ATC were not fully aware of the actual problems that the crew were experiencing
Neither were the crew, probably, since they reported "engine on fire" while said engine was already on the bottom of a lake. Moments previously, they had reported "we lost engines 3 & 4" probably meaning to say they lost thrust (and interpreted as such by ATC) but most likely they were not aware they quite literally
lost them.
The inboard engines on a 747 are not visible from the flight deck, the outboard engines just very barely, and being a cargo there were no reports from the passenger cabin...
