The Blackhawks fail the test of a secret agency named G.E.O.R.G.E. in front of four super-heroes and the U.S. President, therefore they retire and then begin the “New Blackhawk Era”, donning super-hero names, powers and costumes as members of G.E.O.R.G.E. Blackhawk gains the code-name “the Big Eye”, Chuck becomes the Listener, Hendrickson the Weapons Master, Olaf the Leaper, Stanislaus the Golden Centurion, Andre becomes M'sieu Machine, and Chop-Chop becomes Dr. Hands. Note: This story must take place in the 1960s following previous issues, since Lady Blackhawk is still hypnotized and acting as Queen Killer Shark. The uncharacteristic New Era Blackhawks may not have been the real Blackhawks after all, but instead doubles (perhaps shape-changing Martians) who replaced the originals in an untold story, partially in order to drive the real Blackhawks into retirement. The presence of Superman, Batman, the Flash, and Green Lantern in this story is problematic but must be accounted for. It's possible that the roles these four play in the compressed Earth-1 timeline were held by four contemporary and prominent 1960s super-heroes such as Superboy, the Vigilante, Plastic Man, and Air Wave. It is also possible that the four JLAers were sent back through time magically by Felix Faust during the events of Justice League of America #49, which takes place in September, 1977; in this case, Superman would have been able to prove his identity to President Johnson and vouch for his three fellow super-heroes, then unknown to the world, since he was personally acquainted with the U.S. presidents ever since he first became Superboy. Presumably the magical transportation would not have displaced Superboy or the then-teenage Batman, Flash, and Green Lantern (Bruce Wayne, Barry Allen, and Hal Jordan) like ordinary time-travel does.
