Registration Number NC7805

Diesel Down

This airplane is a Lockheed Vega 1, S/N 28 (ATC 49) manufactured on December 11, 1928 by Lockheed Aircraft Corporation, Burbank, CA.  It came with a Wright Whirlwind J5C engine (S/N 9214) of 220HP.  It was a five-place aircraft.

Curiously, the airplane landed first at Tucson on October 30, 1928 (check the Register, you’ll see), a full two months before the record says it was manufactured.  At this visit it was flown by E.L. Remelin. He carried Allan Lockheed and Norman Hall as passengers.  Perhaps this was an example of the product not matching the paperwork for an executive hack?  Regardless, they were eastbound from Burbank, CA to El Paso, TX.

It sold for the first time on November 13, 1928 (again, before it “officially” was manufactured) to Cromwell-Hunt Aero Service, San Angelo, TX.  Carl D. Cromwell was president of Cromwell-Hunt Aero Service.  The Vega was to be used, “for oil business, recreation, taxi service.”

A few months after it was delivered, it suffered an accident on March 4, 1929 at Clarksville, TN.  The pilot, Register signer Embree Hunt, cracked the fuselage in three places.  It was rebuilt at the Lockheed factory using a new fuselage.

NC7805 sold on November 26, 1929 to Cromwell Air Lines, San Angelo, TX.  This was probably just a shifting of resources within the Cromwell-Hunt Aero organization.

Somewhere around 1930 it sold to R.O. Dulaney, Jr. of Fort Worth, TX.  We find the airplane at Tucson for the second time on November 9, 1931 with Dulaney as pilot carrying one passenger.  Their home base was listed as Ft. Worth, but they did not cite their itinerary.

On November 23, 1931 it was sold back to Lockheed Aircraft Corporation, repaired and remodeled.  Lockheed sold it on March 16, 1932 to Mrs. Albert Harold Bromley of Parral, Chihuahua, Mexico.  She, in turn, sold it to C.C. Spangenberger of Dallas, TX on March 26, 1932. 

It is during this quick purchase and resale that we find NC7805 at Tucson for the third and final time on March 17, 1932, piloted by Edward F. Booth.  Booth’s itinerary is from Los Angeles to Dallas.  An easy deduction is that this visit is during the ferry flight from Lockheed Aircraft, via Mrs. Bromley, to its new owner in Dallas.  Pilot Booth (q.v.) seems to have been in an aviation services capacity at that time, and it makes sense that either Lockheed, Bromley or Spangenberger would have contracted with him to ferry this newly remanufactured Vega.

Under Spangenberger’s ownership, NC7805 was given an NX license, painted red and black, and a 240HP Guiberson diesel engine was installed.  Guiberson Diesel Engine Company was based in Dallas, TX.  In May, 1932 the airplane was flown from Dallas to Camden, NJ by Harold Bromley in 13 hours 15 minutes.  He also made a non- stop New York-Los Angeles flight in preparation for a Pacific flight attempt (Seattle to Tokyo), which never took place.

On January 5, 1933 the airplane was sold to Cardiff & Peacock, Ltd. of Bakersfield, CA.  It was converted back to the standard Wright Whirlwind J5 engine.  Six months later, on July 11, 1933, it suffered another accident at Dos Palos, CA and was “washed out.”  No further information.
