Flight Crew Took Evasive Action
Human Factors; Procedure
While flying westbound approximately 8 miles north of P03 at 8500 feet MSL we encountered a small grey UAV (possibly a Hunter) followed by Aircraft Z acting as chase. UAV was slightly below us and crossed in front of us from left to right. Aircraft Z crossed underneath us. Collision avoidance was taken by climbing and turning to the Southwest. Approximately 8 minutes prior to the event I called on CTAF 122.8 of our location over P03 and received no response. After seeing the UAV and Aircraft Z I called once again on 122.8 and no answer was received. The UAV and Aircraft Z continued to the North and no change in altitude or direction was seen.
Pilot took evasive action to avoid a UAV and the chase airplane behind it at 8;500 FT near a local airport.
