Double BS! Did you read the story that I linked to? It was well covered when it first came out, and was also covered by Western media as well.
Maybe the Mach 2 part is BS, but flying around the Su-27 convertable is very plausable.
YOu think these cowboys were flying Mach 2 with the canopy open? I’m not a pilot, but I thought that appearance of the plane’s wings and angle etc. indicated that was not possible.
