Boeing 720B
|
The Boeing 720 was designed to be
a smaller, lighter medium range variant of the
Boeing 707.
Although it just looks like a
smaller Boeing 707 it was dramatically
redesigned and only has the same structural base
as the 707. It was originally named Boeing
707-020 but soon changed to Boeing 720. |
