When Donald Douglas built his first aircraft, the Cloudster, he started with constructionnumber 100, this way he pretended to be an experienced aircraft constructor. When the, then McDonnell-Douglas, company was merged into Boeing nobody cared about those never used first 99 anymore. Some 40,000 aircraft were built in various plants, most of those aircraft are in this list. Any Douglas type built by Boeing can be found in the Boeing Production List. The Boeing types of aircraft built by Douglas (and also including the B-24H's) are of course in the Douglas productionlist......
The USAAF introduced a system to identify the manufacturing plant of their aircraft. For Douglas they were:
DC - Douglas Chicago
DE - Douglas El Segundo
DK - Douglas Oklahoma City
DL - Douglas Long Beach
DO - Douglas Santa Monica
DT - Douglas Tulsa
The aircraft which were built in the former plant of Northrop in El Segundo are in a separate list, because that plant used it's own c/n's, with numbers running parallel with other Douglas sites.
Also included are two MD-90-30's, built in China, that line came to a premature end when MDD ceased to exist. I have also included the Canadair North Star / Argonaut, made up from DC-4 and DC-6 parts, combined with RR Merlin engines.
The C-17A is also in the Douglas list untill it became a "Boeing"-aircraft.
As far as the infamous "double c/n's" are concerned, those aircraft are listed under their correct c/n with the incorrect also shown in brackets. This error only happened on a number of C-47-DK's.
All entries are sorted similar: c/n - type - line number (when used) - all registrations and/or military serials.
