Just a bit of historical trivia. The HP-41C calculator "flew on seven Space Shuttle missions. It could have been used in an emergency to calculate orbit and re-entry information if there were failure of the shuttle main computer systems."

Another source indicates that two HP-41C calculators were on board Columbia. One for Center of Gravity and another for Acquisition of Signals.

The HP-41C price at introduction in 1979 was $295 which is a testament to the wonders of capitalism and the free market. I wonder if the Russians are using any iPhones or iPod touches in their functioning space program?
