Narrative:

I was serving as cabin coordinator. I requested 2 departure releases from radar and was told to place air carrier X in front of and the second aircraft behind a flight of F15's, crossing the SID heading of the departing aircraft. We expected the F15 flight to reduce airspeed to allow room for the 1ST departure. Unfortunately the radar controller thought that the last departure from a previous release was the departure that was to go in front of the F15 flight. The local controller used a vector and altitude restr to increase separation, but not as far as standard separation. We assumed the best and got something less. We should have held our departure on the ground and re- coordinated. Thankfully the WX was cavu and we could work on the problem visually, although if the WX had been IMC we would have been more cautious anyway.

Original NASA ASRS Text

Title: ACR X DEP HAD LTSS WITH 2 MIL FIGHTERS. SYS ERROR.

Narrative: I WAS SERVING AS CABIN COORDINATOR. I REQUESTED 2 DEP RELEASES FROM RADAR AND WAS TOLD TO PLACE ACR X IN FRONT OF AND THE SECOND ACFT BEHIND A FLT OF F15'S, XING THE SID HDG OF THE DEPARTING ACFT. WE EXPECTED THE F15 FLT TO REDUCE AIRSPD TO ALLOW ROOM FOR THE 1ST DEP. UNFORTUNATELY THE RADAR CTLR THOUGHT THAT THE LAST DEP FROM A PREVIOUS RELEASE WAS THE DEP THAT WAS TO GO IN FRONT OF THE F15 FLT. THE LCL CTLR USED A VECTOR AND ALT RESTR TO INCREASE SEPARATION, BUT NOT AS FAR AS STANDARD SEPARATION. WE ASSUMED THE BEST AND GOT SOMETHING LESS. WE SHOULD HAVE HELD OUR DEP ON THE GND AND RE- COORDINATED. THANKFULLY THE WX WAS CAVU AND WE COULD WORK ON THE PROB VISUALLY, ALTHOUGH IF THE WX HAD BEEN IMC WE WOULD HAVE BEEN MORE CAUTIOUS ANYWAY.
