Narrative:

This is an event which ATC would label; ATC controller using anticipated separation. We were cleared for takeoff on runway 14L with an RJ50 on a 3 mi final for runway 22R. We had a normal takeoff short for a light weight B757 going ord-dtw. I rotated prior to the runways 14L/22R intersection. As I called for 'gear up' the tower controller told the rj to 'go around.' I could still see the rj out of the captain's front window. The rj and us were climbing about the same rate of climb. I lost sight of the rj as we continued our departure; but the TCAS showed him with 100 ft and collocated with us. Because we were very busy in the cockpit; we did not think of filing an near midair collision. After reading about the similar situation at bos with air carrier X; I felt compelled to file this safety report. I strongly feel the controllers at airports like ord are putting our lives and our passenger's lives at risk. We could not see the other aircraft to judge the separation; so we relied on the tower controller. In the future; I will not accept a clearance to takeoff unless I have 5 mi separation between aircraft on intersecting runways.

Title: ORD B757 RWY 14L DEP EXPRESSED CONCERN WITH ANTICIPATED SEPARATION USED BY ATC WHEN ARR TO RWY 22R WAS ISSUED GAR TO MAINTAIN SEPARATION.

Narrative: THIS IS AN EVENT WHICH ATC WOULD LABEL; ATC CTLR USING ANTICIPATED SEPARATION. WE WERE CLRED FOR TKOF ON RWY 14L WITH AN RJ50 ON A 3 MI FINAL FOR RWY 22R. WE HAD A NORMAL TKOF SHORT FOR A LIGHT WT B757 GOING ORD-DTW. I ROTATED PRIOR TO THE RWYS 14L/22R INTXN. AS I CALLED FOR 'GEAR UP' THE TWR CTLR TOLD THE RJ TO 'GO AROUND.' I COULD STILL SEE THE RJ OUT OF THE CAPT'S FRONT WINDOW. THE RJ AND US WERE CLBING ABOUT THE SAME RATE OF CLB. I LOST SIGHT OF THE RJ AS WE CONTINUED OUR DEP; BUT THE TCAS SHOWED HIM WITH 100 FT AND COLLOCATED WITH US. BECAUSE WE WERE VERY BUSY IN THE COCKPIT; WE DID NOT THINK OF FILING AN NMAC. AFTER READING ABOUT THE SIMILAR SIT AT BOS WITH ACR X; I FELT COMPELLED TO FILE THIS SAFETY RPT. I STRONGLY FEEL THE CTLRS AT ARPTS LIKE ORD ARE PUTTING OUR LIVES AND OUR PAX'S LIVES AT RISK. WE COULD NOT SEE THE OTHER ACFT TO JUDGE THE SEPARATION; SO WE RELIED ON THE TWR CTLR. IN THE FUTURE; I WILL NOT ACCEPT A CLRNC TO TKOF UNLESS I HAVE 5 MI SEPARATION BTWN ACFT ON INTERSECTING RWYS.
