We did, my brother thought it was insane that he trained as conscripts aircraft mechanic on J-35 Draken (Dragon), then the Swedich Draken was planned stand down. Not that Finland did have J-35 Draken, and Sweden did saved parts and whole? aircraft so it could be transferred to Finland if needed.
During the vinter war Sweden transfer about 1/3 of its fighters to Finland... only volunteers but with the Government blessing and full support.
