It was so much better than anything else, so revolutionary, it was almost shocking. I imagine TI engineers sighing in dismay when they realized that HP was shipping a product that was better even than what they, TI, only had on the drawing board.

At that time I'd been a young first officer (aka Copilot) on a Boeing 707. Long range flight planning was done by looking at about 500 pages of structured numbers. With an HP97 I statistically evaluated all these numbers and finally ended with a magical formula for my HP41C. Then I could select from the various variables take off or landing weight, the fuel available or necessary, the wind component or feasable -- which of the remaining data I'd like to calculate. This was somewhat easy to progranm on the HP41 with those specific flags for input or not.

I was asked to provide this programme for a TI59 also. I failed to do so, as on the TI59 a completely different approach would have been neccessary. And I was not overly willing in doing so.
