Editing Lockheed Model 9 Orion (section)

==Design==
The Orion was the last design using many identical elements from the Lockheed designs preceding it. It primarily used all the elements of the [[Lockheed Altair|Altair]], but included a forward top [[cockpit]] similar to the [[Lockheed Vega|Vega]], plus the [[NACA cowling]] introduced in the [[Lockheed Air Express|Air Express]].<ref name="eden">{{Cite book |url=https://archive.org/details/completeencyclop0000unse_z7c1 |title=The complete encyclopedia of world aircraft |date=2002 |publisher=[[Barnes & Noble]] |isbn=978-0-7607-3432-2 |editor-last=Eden |editor-first=Paul |location=[[New York City]] |page=899 |oclc=1301969271 |ol=8013422M |access-date=2022-03-21 |editor-last2=Moeng |editor-first2=Soph |via=[[Internet Archive]] |language=en}}</ref> Lockheed used the same basic fuselage mold and wing for all these wooden designs (the [[Lockheed Explorer|Explorer]] wing was unique), hence the close similarities between them. The Orion featured an enclosed cabin with seating for six [[passenger]]s. The Orion received its [[Type certificate|Approved Type Certificate]] on 6 May 1931.<ref name="Francillon">{{Cite book |last=Francillon |first=René J. |url={{GBurl|j88pAQAAIAAJ}} |title=Lockheed Aircraft Since 1913 |date=1987 |publisher=[[Naval Institute Press]] |isbn=978-0-87021-897-2 |location=[[Annapolis]] |lccn=87061414 |oclc=243306933 |ol=2411247M}}</ref>
