Vintage work crew photos

I wonder how that skinny kid on top of that aircraft pulled that long belt of 50 caliber all the way up the side of that fuselage without doing any damage to the aluminum skin?? Also, if you pull up the full sized photo, and zoom in on the guy on the prop, he looks like he is about to fall asleep!!

Supposedly, expending the entire belt on a target gave rise to expression "the whole nine yards". I'd estimate .50 cal space 1.4" center to center in linked belts, which equates to around 230 rounds...
True or not, that definition is good enough for me.
