ELECTRA
HISTORY
In the summer of 1932 Robert Gross determined that the reborn Lockheed
should start fresh with the very latest type of aircraft. Initially, it
was to embody the usual low-drag and single engine design, but other development
dictated major changes.
In February 1933 Boeing launched it's revolutionary model 247 which
was the first low-drag twin engine all metal transport. Seating 10 passengers
in comfort, it was 50 MPH faster than any other airliner in service. Five
months later Douglas introduced their DC-1 which was even faster and had
more payload than the Boeing. The impact of these two, and later the improved
DC-2 compelled Lockheed to rethink their new plane and design a twin engine
transport that would surpass it's competitors.

It was decided that the model 10 was laid out as a twin engine, all
metal, ten passenger plane, with a crew of two and a toilet compartment.
Baggage could be loaded into the nose, and sometimes also into the rear
fuselage. There were also small baggage areas in the tops of each wing.
It had an all metal stressed skin fuselage, motor driven retractable landing
gear, and retractable flaps, something that the Boeing did not have. It
was also faster than the Boeing, and competitive with the DC-2.
 
Marshall Headle ... ... and
his team.
The first Model 10 Electra was tested by Marshall Headle at Mines
Field, Los Angeles on February 23, 1934. Northwest Airways and Pan American
placed the first orders and it first went into service with Northwest in
June 1934, and within twelve months they operated a fleet of thirteen aircraft.
Eventually four main versions of the Electra were produced. L 10-A
with Pratt and Whitney Wasp Junior R-985SB/SB-3 engines. The model B with
Wright Whirlwind R-975-E3s, the Model C with Wasp SC-1s, and the Model
E with Wasp R 1340 S3H-1 engines.

The Electra was an immediate success. At it's introduction it was
one of the fastest airliners available and orders flowed in from all over
the world, with eventual sales to 23 airlines in 13 countries.
The total number of Model 10A was 107 the model B was 19, the model
C was 8, and the Model E was 15. In all, 115 went to airlines, 7
to the US Government, 2 to the Argentine Government, and 25 to private
customers.

The last Airline to purchase the Electra was LAN Chile, in July 1941.
During WW II. many Electras were confiscated and used by UAAC and
RAF. Some of the 10 Polish LOT Electras got into German hand and were used
in different transportation units of the German Luftwaffe.
The military version of the L-10A: Y1C-36 of the US Army Air Corps
(UAAC)
Several Electras achieved fame. The first round-trip of the Atlantic
by an airline was by an Eastern Airlines L-10 A in May 1937, carrying first
film of the Hindenburg disaster, and returning to the US with films of
the coronation of King George VI. ... and of course it was a Lockheed Electra
L 10 E that Amelia chose for her ill fated around the world flight
in 1937.
[Contrary to other statements the British Prime Minister
Chamberlain wasn't flown to Munich in September 1938 to meet with Adolf
Hitler in a British Airways L-10-A but in a L-14 (G-AFGN)].

The Electra was finally replaced by the success of the Douglas DC-3
in airline service, but many Electras were used by companies as executive
aircraft, and it was still in service as late as 1965 in regular service
by Provincetown Boston Airline on the route between Boston and the island
community on the tip of Cape Cod.
As of August 1998 there are three model 10-A's still airworthy, and
one Model E. It is owned by Ms. Linda Finch in San Antonio Texas, and she
flew her Electra on a successful recreation of Amelia Earharts around the
world flight.
