This is very sad to hear, Jorge ...
But that is a general problem with allmost all aviation museums. People are not very interested this times, in old planes ... They forget, the sacrifices of the people flying them in the past! Sacrifices, to ensure that all we now, can live in freedom and peace.
In Greece, the HAF-Museum is still considering a active Air Force unit. So, no problem to find people and money (well, that is a little bit of a problem

) to keep the planes and helicopters in a relatively good condition, under the current climatic conditions (strong sun)!
Maybe that would be a sollution also for Ecuador? To put the Museum under charge of the FAE, as a active unit?
