Wow, six different types at once. You just have to tell us what the types were now.
Sounds pretty interesting.
I guess it depends on what types you are current on, it would be difficult to stay current on six big jets, but on smaller airplanes it is a different story.
Reading Clunk's post reminded me of flying a lot of different aircraft for the same company and randomly going from one to another day after day.
Little single engine trainers, an Apache, a Beech 18, a Dehavilland Dove and a couple of helicopters.
And at night I rode my motorcycle home.....with no check list.
