Narrative:

On takeoff bct, runway 23, observed other high wing fixed aircraft on opposite side runway going (taxiing) opposite direction. First observed other aircraft just after lift-off and passed well above and right. No radio calls heard on unicom frequency 122.8. No aircraft heard or observed in pattern prior to initiating takeoff roll. Bct is an uncontrolled unicom only airport. Radio calls need to be made in a timely manner. I know I'll be listening and looking a little more closely next time. Maybe a landing light on for takeoff would give added visibility

Title: POTENTIAL CONFLICT. UNAUTH TKOF AT NON TWR ARPT. TKOF ON OCCUPIED RWY.

Narrative: ON TKOF BCT, RWY 23, OBSERVED OTHER HIGH WING FIXED ACFT ON OPPOSITE SIDE RWY GOING (TAXIING) OPPOSITE DIRECTION. FIRST OBSERVED OTHER ACFT JUST AFTER LIFT-OFF AND PASSED WELL ABOVE AND R. NO RADIO CALLS HEARD ON UNICOM FREQ 122.8. NO ACFT HEARD OR OBSERVED IN PATTERN PRIOR TO INITIATING TKOF ROLL. BCT IS AN UNCTLED UNICOM ONLY ARPT. RADIO CALLS NEED TO BE MADE IN A TIMELY MANNER. I KNOW I'LL BE LISTENING AND LOOKING A LITTLE MORE CLOSELY NEXT TIME. MAYBE A LNDG LIGHT ON FOR TKOF WOULD GIVE ADDED VISIBILITY
