I saw those Tomcats a few times at the Van Nuys, CA Airshow in 97-98 ( I'm pretty sure), definitely before 9/11 when security went ape-$hit!!
As the pilots were leaving they kept raising & lowering their front landing gear like they were bowing, Then took off at full afterburner. One regular pass, one inverted!! Good times!!
Surprised no one has tried this color scheme for any Valk.
