Is there anybody flying on a B-52 that was born before the plane was built?
(btw designed with slide rules, drawn with pencil on vellum, and the BOM was in 3-ring binders, LOL)
There must be at least 1 person.
That's the way it was done when I started a career in engineering. Our first computer was a time share with 110 baud access via teletype, programing language was FORTRAN II. I've lost count of the number of programming languages and operating systems I've run through. Things really got exciting when we started 3D solid modeling and rapid prototyping. Amazing what 40 years can bring...
