In the flight controls group, I was probably the first engineer to use a 
computer. I wrote my own programs to do things like matrix inversions.

The rest used calculators, and a method of using mechanical drafting tools to do 
calculations, which I had no idea how to do.

The 757 was the last airplane to have a full size wooden mockup built. The 
mockup was to check clearances so that two assemblies didn't occupy the same 
space. Internal space is awfully tight on a jet, and everything has to fit in 

Computerized drafting was coming, but it wasn't good enough at the time. Pen and 
ink had its last stand with the 757.
