The second images shows a Hudson approaching for landing, flaps down. Note the lack of tail markings.
The Hudson was a light bomber and coastal patrol aircraft based on the Lockheed Model 14 Super Electra, a design that was made famous by Howard Hughes' record-setting round-the-world flight from July 10-14, 1938. The design also led to the later Lockheed Ventura.
When the U.S. started delivering Hudsons to the RAF, American neutrality in the European conflict complicated the process. The aircraft were flown from Burbank to the U.S.-Canada border, where they were towed across by tractor or even horse-team, and then disassembled and loaded onto a ship for the trans-Atlantic voyage. On October 8, 1939, a Hudson became the first RAF aircraft (though not the first British plane) to shoot down a German opponent.
