Before somebody jumps the gun about the draft dodging comment Iīd recommend reading the article from Turun Sanomat posted on their (virtualpilots) site.
One serious problem with the article itself is that very great emphasis is laid on memories of very old pilots. If you read the transcripts of various interviews they have conducted, some of the crucial questions are very "leading the witness". Furthermore, apart from Karhila the pilots they interviewed (because the "big guns" are no longer with us) are mostly "also rans", folks that didnīt have really extensive combat experience.
Perhaps a more authoritative approach would have been examining wartime combat reports to see how the pilots them evaluated their kites. But that means work, work and work.
