I've already done a little bit of googling on this topic but it really
didn't net much information.

I'd like to learn more about the various roles and missions the B-57 was
used for in Viet Nam. Can anyone point to written material or resources
that might be worth having a look at?

I have a friend who was a USAF nav in the 50s who claims the plane was
quite manuverable for something of its size. I'd like to learn more.

Thanks

Chris
