I don't think there's anything wrong with any kind of "hall of fame" celebrating the greats of a particular nation's aviation achievements - so long as they admit that's what they are doing.
But, if you start to introduce people from outside your own parish, you really need to be less partisan.
The area this is most obvious I think is actually in Space. Most space related material we read in the English language is US originated, and thus tends to forget that the Russians managed the first man in space, the first two-men in space, the first orbit, first spacewalk, landing on the moon, space shuttle flight, space station... (Basically the Yanks pipped them for a manned moon landing and a more successful shuttle, but that's about it).
