Narrative:
Small transport X on a visibility approach to plb. Approach clearance was cancelled, and small transport X was assigned a heading and altitude for sequencing with a military bmb Y. Small transport X cancelled his IFR clearance and turned on course to the airport VFR. Bmb Y was in the overhead pattern at plattsburg AFB located 4 mi southeast of plb. Small transport X continued his VFR descent. The bmb Y climbed from 2000' to 2300', pattern altitude for pbg. Small transport X was instructed to maintain 2500', and although traffic was given no conflict alert was issued. Small transport X was also established in the plattsburg AFB air traffic area west/O coordination.

Title: SMT X HAD AIRBORN CONFLICT WITH BM Y. SEE AND AVOID CONCEPT. SMT X ENTERED PBG CTLR ZONE WITHOUT COORD. OPDEV.
Narrative: SMT X ON A VIS APCH TO PLB. APCH CLRNC WAS CANCELLED, AND SMT X WAS ASSIGNED A HDG AND ALT FOR SEQUENCING WITH A MIL BMB Y. SMT X CANCELLED HIS IFR CLRNC AND TURNED ON COURSE TO THE ARPT VFR. BMB Y WAS IN THE OVERHEAD PATTERN AT PLATTSBURG AFB LOCATED 4 MI SE OF PLB. SMT X CONTINUED HIS VFR DSNT. THE BMB Y CLBED FROM 2000' TO 2300', PATTERN ALT FOR PBG. SMT X WAS INSTRUCTED TO MAINTAIN 2500', AND ALTHOUGH TFC WAS GIVEN NO CONFLICT ALERT WAS ISSUED. SMT X WAS ALSO ESTABLISHED IN THE PLATTSBURG AFB ATA W/O COORD.
