Narrative:

I observed aircraft X and Y being controled by sector 12, 1 climbing through FL205, the other descending through FL205 with plus or minus 4 NM between them -- an operational error. I saw my supervisor watching the operational error occur, and I remarked that it was close, and asked if operational error detection program (snitch) went off. He said nothing, and left. I believe management covers up errors at their discretion, and reports others, depending upon circumstances (operational error depection program not catching the error, etc).

Original NASA ASRS Text

Title: ACFT X CLB THROUGH OCCUPIED ALT HAD LTSS FROM ACFT Y. SYS ERROR.

Narrative: I OBSERVED ACFT X AND Y BEING CTLED BY SECTOR 12, 1 CLBING THROUGH FL205, THE OTHER DSNDING THROUGH FL205 WITH PLUS OR MINUS 4 NM BTWN THEM -- AN OPERROR. I SAW MY SUPVR WATCHING THE OPERROR OCCUR, AND I REMARKED THAT IT WAS CLOSE, AND ASKED IF OPERROR DETECTION PROGRAM (SNITCH) WENT OFF. HE SAID NOTHING, AND LEFT. I BELIEVE MGMNT COVERS UP ERRORS AT THEIR DISCRETION, AND RPTS OTHERS, DEPENDING UPON CIRCUMSTANCES (OPERROR DEPECTION PROGRAM NOT CATCHING THE ERROR, ETC).
