I first snapped this DC-3 when it was CF-ICU with Spartan Air Services. That was at Gatwick/UK on 04Aug63. Here it is with Continental Aviation of Oklahoma and still doing survey work. Note the 'bomb' under the fuselage and roof antennas for dual ADF used for cross-checking position in the pre-GPS era. Last known stored for spares use with the Vintage Flying Museum at Meacham Field, Fort Worth, TX since 2010.
