Don't know much about the TriStar, do you?
Certainly not as much as I used to when I operated it, since then I've had to learn:
DC10 3 variants
A300B4
Tornado 2 variants
Hawk 6 variants
So memory isn't as good as when I operated and taught/wrote about one type at a time.
There again, if 5% of what I said is wrong, it means 95% is right.
You stick to your "world of 5%", the rest of us will concentrate on the 95%.
Have a nice day . . .
