Narrative:

I was working the elx sector at ZAU during moderate traffic when flow control came up behind me to inform me of a newark, nj, in-trail problem with 3 aircraft in 3 different sectors all abeam of each other and needing 15 mi in-trail. When I turned back to the sector I had lost my train of thought, forgetting about a FL390 problem. I had begun the coordination needed for the newark problem when the FL390 problem was brought to my attention. I turned air carrier X to a 340 degree heading and climbed to FL410. I attempted several times to descend and turn air carrier Y but could not get an answer. The aircraft passed 2.7 mi and 800 ft. Supplemental information from acn 407385: we (air carrier Y) received an RA with a climb command. We immediately started climb, we saw the traffic on TCASII at which time the controller commanded a right turn with a descent. We stayed with the climb knowing a change to a descent would put us on top of the traffic. We visually saw the traffic pass by our left side 1-3 mi out. Supplemental information from acn 407125: we were in level cruise at FL390, proceeding direct to the roberts VOR. ZAU said 'air carrier X, turn right to 340 degrees, climb to FL410.' since this was approximately a 100 degree heading change, and we were already at or near our maximum altitude for our gross weight, I asked the controller to 'confirm' that the clearance was for air carrier X. He did, so I (air carrier X) directed the first officer to turn and climb. I then heard air carrier Y heavy report that they were responding to an RA. Our TCASII then gave us an RA to 'climb.' our relief pilot then pointed out the traffic at 11 O'clock position.

Title: 2 B767 ACFT, APCHING RBS VOR FROM OPPOSITE DIRECTIONS WERE BOTH AT FL390. ACR Y RESPONDS IMMEDIATELY TO A TCASII RA COMMANDING A CLB. AT THIS TIME THE CTLR SEES THE PROB AND INSTRUCTS ACR X TO CLB AND TURN. ACR X, WHILE ASKING THE CTLR TO CONFIRM THE INSTRUCTION, ALSO RECEIVES A TCASII RA COMMANDING A CLB. BOTH ACFT SIMULTANEOUSLY OBSERVE EACH OTHER PASS.

Narrative: I WAS WORKING THE ELX SECTOR AT ZAU DURING MODERATE TFC WHEN FLOW CTL CAME UP BEHIND ME TO INFORM ME OF A NEWARK, NJ, IN-TRAIL PROB WITH 3 ACFT IN 3 DIFFERENT SECTORS ALL ABEAM OF EACH OTHER AND NEEDING 15 MI IN-TRAIL. WHEN I TURNED BACK TO THE SECTOR I HAD LOST MY TRAIN OF THOUGHT, FORGETTING ABOUT A FL390 PROB. I HAD BEGUN THE COORD NEEDED FOR THE NEWARK PROB WHEN THE FL390 PROB WAS BROUGHT TO MY ATTN. I TURNED ACR X TO A 340 DEG HDG AND CLBED TO FL410. I ATTEMPTED SEVERAL TIMES TO DSND AND TURN ACR Y BUT COULD NOT GET AN ANSWER. THE ACFT PASSED 2.7 MI AND 800 FT. SUPPLEMENTAL INFO FROM ACN 407385: WE (ACR Y) RECEIVED AN RA WITH A CLB COMMAND. WE IMMEDIATELY STARTED CLB, WE SAW THE TFC ON TCASII AT WHICH TIME THE CTLR COMMANDED A R TURN WITH A DSCNT. WE STAYED WITH THE CLB KNOWING A CHANGE TO A DSCNT WOULD PUT US ON TOP OF THE TFC. WE VISUALLY SAW THE TFC PASS BY OUR L SIDE 1-3 MI OUT. SUPPLEMENTAL INFO FROM ACN 407125: WE WERE IN LEVEL CRUISE AT FL390, PROCEEDING DIRECT TO THE ROBERTS VOR. ZAU SAID 'ACR X, TURN R TO 340 DEGS, CLB TO FL410.' SINCE THIS WAS APPROX A 100 DEG HDG CHANGE, AND WE WERE ALREADY AT OR NEAR OUR MAX ALT FOR OUR GROSS WT, I ASKED THE CTLR TO 'CONFIRM' THAT THE CLRNC WAS FOR ACR X. HE DID, SO I (ACR X) DIRECTED THE FO TO TURN AND CLB. I THEN HEARD ACR Y HVY RPT THAT THEY WERE RESPONDING TO AN RA. OUR TCASII THEN GAVE US AN RA TO 'CLB.' OUR RELIEF PLT THEN POINTED OUT THE TFC AT 11 O'CLOCK POS.
