Narrative:

On takeoff roll on runway 15 at bur airport, both myself (captain) and my first officer noticed a light propeller aircraft directly ahead of us at approximately 50 ft altitude on takeoff leg (or missed approach), on an intersecting runway. Our aircraft was at approximately 90 KTS on takeoff roll as the propeller craft passed right to left in our field of view at a lateral distance of approximately 2000-3000 ft. By the time our aircraft reached takeoff speed, the propeller plane was well clear and posed no danger. Lateral clearance at the time of our liftoff, however, is estimated at 2000-3000 ft.

Title: DEPARTING B737 OBSERVES ACFT PASS IN FRONT WHILE ON TKOF ROLL.

Narrative: ON TKOF ROLL ON RWY 15 AT BUR ARPT, BOTH MYSELF (CAPT) AND MY FO NOTICED A LIGHT PROP ACFT DIRECTLY AHEAD OF US AT APPROX 50 FT ALT ON TKOF LEG (OR MISSED APCH), ON AN INTERSECTING RWY. OUR ACFT WAS AT APPROX 90 KTS ON TKOF ROLL AS THE PROP CRAFT PASSED R TO L IN OUR FIELD OF VIEW AT A LATERAL DISTANCE OF APPROX 2000-3000 FT. BY THE TIME OUR ACFT REACHED TKOF SPD, THE PROP PLANE WAS WELL CLR AND POSED NO DANGER. LATERAL CLRNC AT THE TIME OF OUR LIFTOFF, HOWEVER, IS ESTIMATED AT 2000-3000 FT.
