I just LOVE those old US Army instructional videos! Torque specs: two fingers on an 8" wrench
Seems like a pretty heavy aircraft for a fighter plane but I guess it must have been effective---I think it was utilized quite a bit in its day. If I was piloting one of the ones assembled in the field I'd sure hope it wasn't the first time that crew chief read those instructions. Gotta love the sound of that radial engine when fired up!
