Anyone know why the OKCPD copter was flying a repeated pattern around S.W. 104th & May area--could have extended a bit farther in all directions, hard to tell exactly--from approx. 3:30 AM to 5:30 AM this morning (12-27)? We never heard any sirens, which usually accompany the copter if it is in "search" mode. For the "search" to last that long (with one break, apparently to go refuel), we figured something significant had to have happened.

Really curious and would appreciate any info.
