I read that Kelly Johnson said no engineer could have his desk located > 50 yards from the airframe build bay.

Astonishing, with no computers his team could kick out a major design with working prototypes in a year. It took every company I worked for that long to do a design study. Of course, he kicked the military out until he was done. Nobody can do that today. Every time a colonel shows up we spent two weeks prepping, three days presenting and another two weeks cleaning up the mess and answering incredibly stupid questions in microscopic detail. The military is its own worst enemy.
