Gopher 01,
Goose. Yep ISTR you and MG there.
External tanks. It's interesting that they couldn't let the drivers airframe play with a clean airframe back then. As I remember we had to put a red sticker on the instrument panel to remind them they were driving a longer Albert.
I believe the J can be used both with and without the externals, so the thinking has changed.
Hope you are well.
