Indeed a huge difference, Thorsten. I would have thought they were closer as far as the software is concerned; just wood, some enhancements and more speed for the Expert... But the evidence is the evaluation management evolved a lot from 1984 to 1985. And surely did not freeze later on, that's why it is a struggle to identify the legacy "PSH effect" in the next Kittinger devices.
My conclusion: the Super Constellation is one of its own, a singularity blessed with some flash of genius!
