Aviation Museum Society, Finland invited the British RAF warpilot Wing Commander Robert W. Foster, DFC, AE, to Finland in June 2004. Mr. Foster, a true British gentleman, blessed us with two most interesting lectures, the first one at Finnish Air Force Museum at Tikkakoski, the second at Finnish Aviation Museum at Vantaa.
