No. 42 Squadron (Finland)

Under the command of Captain Armas Eskola, the crews of its three flights were transferred to Juva on February 23 to wait for their British-purchased Blenheim fleet.

After a short period of training, the squadron took part in bombing missions from March 4, 1940, fighting the Russian invasion of the Vyborg Bay .

On April 25, 1940, seven aircraft and their crew transferred to Pori Airport for a month-long mission to fly surveillance flights in the Baltic Sea and the Åland Islands.

The squadron aircraft also performed aerial photography during the truce: on October 13 and November 11, 1940, the Soviet base at Hanko and the Russian airports in the Karelian Isthmus were photographed.

The squadron flew its first military flight on June 28, performing reconnaissance and filming the sections Parikkala-Rautu and Vyborg-Sortavala with a single aircraft.

On July 3, the squadron was transferred back to Lake Luonetjärvi, with the task of supporting the field army, which was preparing to attack at the Karelian Isthmus.

It conducted bombardment and reconnaissance missions against the retreating German troops, flying out from the Paltamo, Pudasjärvi and Kemi airports.

Following the lifting of the flight ban imposed by the Allied Control Commission in the fall of 1944, the squadron continued to operate from the Luonetjärvi base, training Blenheim crews up until August 1, 1945.
