June 18, 1940 - (Soviet Occupation) - the non-flying members of the Aviation Regiment gather at their headquarters on
Daugavgrivas street, but V.Krastins is assigned as the duty officer at Spilve because he speaks Russian well. He remained
at this post for a number of days.
July-August, 1940 - a delegation of the Aviation Regiment travels to the Aviation Festival in Moscow, presumably to familiarize
themselves with Soviet aviation technology and practices. This delegation is led by Viktors Krastins.
1940-1941 - Serves with the Latvian Squadron of the Soviet 24th Territorial Corps, stationed at Gulbene and flying the SV-5s.

collaborator and informer against his Latvian colleagues.
June 1941 - when the Germans attacked the Soviet Union, the Gulbene Squadron received orders to withdraw into Soviet
territory. Many of the latvians used this opportunity to escape to the other side, while others were taken into the Soviet Union against
their wishes. Krastins willingly went with the Squadron to Rzhev (though he did manage to crash the KOD-1 on takeoff from Gulbene).
