Narrative:

H/C141-B24 champ B24 sie; LR35-A300 champ A300 bergh. The real problem was non radar controller did not catch only 4 mins converging at champ (based on pilot estimates). LR35 was earlier than his estimate so no time converging. Neither pilot reported seeing each other. I am concerned pilots rely too much on ATC and therefore don't scan for traffic on their own. I don't see how the LR35 could have missed seeing the C141 other than they just weren't looking. Aircraft not TCASII equipped, flying in non radar airspace should be extra vigilant with periodic scans for traffic. Mistakes within the ATC system will always occur. A pilot's awareness is his last defense against loss of separation.

Title: ARTCC CTLR HAS LTSS WITH 2 ACFT COMING FROM A NON RADAR TO RADAR ENVIRONMENT.

Narrative: H/C141-B24 CHAMP B24 SIE; LR35-A300 CHAMP A300 BERGH. THE REAL PROB WAS NON RADAR CTLR DID NOT CATCH ONLY 4 MINS CONVERGING AT CHAMP (BASED ON PLT ESTIMATES). LR35 WAS EARLIER THAN HIS ESTIMATE SO NO TIME CONVERGING. NEITHER PLT RPTED SEEING EACH OTHER. I AM CONCERNED PLTS RELY TOO MUCH ON ATC AND THEREFORE DON'T SCAN FOR TFC ON THEIR OWN. I DON'T SEE HOW THE LR35 COULD HAVE MISSED SEEING THE C141 OTHER THAN THEY JUST WEREN'T LOOKING. ACFT NOT TCASII EQUIPPED, FLYING IN NON RADAR AIRSPACE SHOULD BE EXTRA VIGILANT WITH PERIODIC SCANS FOR TFC. MISTAKES WITHIN THE ATC SYSTEM WILL ALWAYS OCCUR. A PLT'S AWARENESS IS HIS LAST DEFENSE AGAINST LOSS OF SEPARATION.
