Blackhawk is confusing

Blackhawk is a Quality Comics character that has a long and eventful publication history, with several different versions which aren't exactly the same. The main team is, in name and appearance, more or less the same in all versions. Blackhawk has been an American, a Pole, an American of Polish extraction and a Pole again. Members of his team have changed names and nationality several times. The Blackhawk Squadron was active after the war as Blackhawk Airways, Blackhawk Express or Blackhawk Industries, or a combination thereof. Two villains named Killer Shark were mixed up. Timelines were altered in Zero Hour. And writers just stopped caring.

Timeline

 * 1941: Blackhawk of the Quality Universe is created by Will Eisner.
 * 1957: As DC takes over Quality's stock, it continues publishing Blackhawk stories with . This version isn't firmly established as Earth-One until 1967.
 * 1959: Introduction of Lady Blackhawk.
 * 1967: The Blackhawks, after being reminded they're outdated as a concept, adopt ridiculous superhero names. Well, everyone except Blackhawk, he's supposed to be cool.
 * 1973: Along with the other Quality stock, Blackhawk is introduced on Earth-X. Later appearances establish he is originally from Earth-Two. This version of Blackhawk is Polish, as opposed to earlier versions, who were American.
 * 1976: After being cancelled at #243 in 1968, the series is picked up again with the "New Blackhawk", only to be canceled again at #250. This era is later designated non-canon.
 * 1983: Mark Evanier picks up the series at #250, setting it into World War II and rewriting most history. Chop-Chop's old origin is changed and Lady Blackhawk is absent.
 * 1988: Following the Crisis on Infinite Earths, Howard Chaykin takes the rains and starts with a fresh series. He gives many members new origins and names, and considerably more characterization. They are a World War II era team, with their last recorded adventure in 1951
 * 1989: Blackhawk, the old Earth-Two version rather than the Chaykin version, is established as a Freedom Fighters member.
 * 1994: Zero Hour messes things up. Big time. The Chaykin team is largely written out of continuity when Zinda Blake, the original Lady Blackhawk, is plucked out of the timeline. Subsequent appearances muddle things up even further. With the exception of Blackhawk himself, who is a combination of Earth-One and Chaykin's Janos Prohaska, the team is the Evanier-era group, plus Zinda Blake. Unlike earlier versions, this Zinda was active with the Blackhawks during World War II up until at least 1950. Legacy cameos muddle the post-war timeline, though they seem to have been active until the formation of the Justice League.
 * 2001: President Luthor forms his own, new Blackhawk Squadron.
 * 2011: As part of the New 52, the updated Blackhawks, the Blackhawk Program, is introduced.
