There was an article in flypast or Aeroplane mag a few years ago showing a load of spads, a couple or providers etc if memory serves me correctly, it also showed rows of unopened radial engines on some dockside, they popped the lid on one and it was corroded, they popped it on another and there was a hiss as the seal broke and it was mint, they said there was a row of them and they were I believe spad ones.
Here you go,
Boeing CH-47A Chinook helicopters left behind in Vietnam.
