N733US Boeing 720-051B Northwest Orient Airlines JFK 09JUL70

Replacing an earlier scanned slide with a better version 06-Sep-15.


Although the airline was called Northwest Orient at this time, the word 'Orient' didn't appear on aircraft which operated only on services within North America.


Ordered by Northwest Orient Airlines, N733US was initally leased by Boeing to TWA Trans-World Airlines in Sep-61 (with Northwest's agreement) as N795TW. Returned to Boeing in Oct-62, it was leased to Northwest Orient as N733US. Northwest Orient bought it in Jul-68. It was sold to Maersk Air Denmark in Nov-72 as OY-APZ (originally it was to be OY-APP which wasn't taken up). It was wet leased to Nigeria Airways over the Christmas/New Year period in Dec-74/Jan-75 and in Nov-79 it was leased to Trans European Airways Belgium as OO-TYA, returning to Maersk Air in Jan-80 as OY-APZ again. In Feb-81 it was sold to Conair of Scandinavia who operated it until Nov-87 when it was sold to AirXport. They immediately sold it on to Allied Signal Inc as N720GT for use as an engine testbed. It was used for testing the Allied Signal AS900 engine which was attached to the right side of the forward fuselage. It was re-registered N720H in Feb-00 and Allied Signal were merged into Honeywell International Inc in Dec-00. The aircraft continued in service as an electronics testbed with Honeywell until it was retired at Phoenix, AZ, USA, in Jan-08 after flying for 47 years. It was broken up at Phoenix in Jun-08.
