I don't think that I would have liked to bumble over the Atlantic in a Connie at heights not above all the weather and without weather seeking radar etc.
Thus far, no a/c I have really missed. Looking through my virtual logbook (a spreadsheet) I have tallied a/c by individual models where I have been able to recall them, as I have only collated this data for the last 20 years and had to think back and research what I have been on.
For example, I
think I have been on the 727-100 as well as the -200 but am not sure, so have just marked it as one entry. On the other hand, I have done the 747 -100-200-300-400-SP (not the Combi) and so they count as five entries. So for all commercial flights (down to a Fairchild Metroliner that I recall and a small Cessna 12 seater that I don't) it's 49 different models/types. Of which 11 were prop (piston and turbo). So I've been very lucky.
