Thanks for the video posting.

My uncle was a P-47 crew chief during WWII so he probably spent some time doing exactly what the video illustrates.

He loved the P-47 and his home was adorned with numerous photos. As a kid I was too shy and respectful to ask questions then and as a teen was too busy chasing girls to ask later. He is long gone now and I regret not spending some time with him once I matured a bit.
