It was not derelict at Lisbon, the report actually said in poor condition but this probably not quite correct as it flew on to Gando Airport, Las Palmas and was observed there in 1969. It very common for spotters to exaggerate how bad an aircraft is – quite often it is being worked on and parts are missing and as in this case the sighting of “in poor condition” became "fate unknown, seen derelict Lisbon 1968 " with no actual justification.
It was next recorded at Gando Airport, Las Palmas in 1969, but had gone by 1972.
The photograph taken in 1969 shows it stripped of paint, all the flying control surfaces have been removed as has the tail cone, fin tip and at least the starboard engine. It looks to as if it was being overhauled and perhaps abandoned during the process for reasons we don’t know. Or perhaps it was flown out after the work on it was competed. If it was just being stripped for spares why remove the paint?
This sighting at Gando Airport is a very good example as to why I need a constant flow of sightings to build up a picture of what was actually happening.
