411A - a very cynical view!
Many of the wonderful people involved in the airlift did so for a higher, arguably more noble reason. I was fortunate enough to be taught in school by a Marist Brother who served some time loading and unloading aircraft during the airlift. He was an amazing man, very modest and motivated to 'make a difference' as he put it.
Money isn't everything - but I'll grant you it helps!
