Who were these guys and where are they now?

Something that has always intrigued me about the picture in the previous post is the presence of the three guys in the bottom of the shot. I enlarged and cropped them this time, just to see if more can be discovered.

Who are they? Possibly Martinair employees? Mechanics perhaps, at least the two on the right, judging by their cover alls. The one on the left a supervisor perhaps. What were they doing?

And, even more intriguing, where are they now? The young man on the far right appears to be in his early twenties. That would make him in his early sixties today. Possibly retired, grandchildren, health problems, false teeth, etc. The other two appear even older, could be approaching seventy.

Sometimes life just seems to evaporate in the twinkling of an eye.
