That was a good episode. One of the better ones of the third season. James Wainwright (who played the washed-up astronaut in the Five-O episode “Shake Hands with the Man on the Moon”) plays the prison escapee who has an axe to grind with Magnum. I agree this would have been a good episode for Jack Lord to guest star and work with Magnum (though knowing McGarrett I can’t imagine him being very cooperative with a PI, a civilian). But he certainly could have had a cameo and given Magnum some info about the jailbreak. Alas it was not meant to be. Jack pretty much retired once Five-O wrapped. But then Kwan Hi Lim was always a special treat as Lt. Tanaka (a quirky Columbo-type) who would provide occasional help to Magnum. So I can’t complain.
