     The XHRP-1 'Flying Banana' first flew in 1947, and led off a whole series
of counter-rotating propeller helicopters built by the Boeing Company.
Currently we produce the CH-47D 'Chinook' helicopter, used by the US Army,
and a commercial version called the 234.  The model 234 does things like
fly people to offshore oil rigs.

     Our helicopters are made in Philadelphia, PA by the Boeing Vertol
Company, which employs about 5000 people.
