Narrative:

Following B747 on visual approach to runway 26L at ont at night. As the B747 landed, another aircraft reported possible tires blowing on the B747. We requested runway 26R, but tower was unable to clear us to land on that runway. I elected to go around to avoid landing on or hitting possible debris from the B747 tires. We were instructed to enter a left downwind and once established on the downwind leg, tower instructed us to execute a 360 degree turn for spacing. In the turn we may have entered the class D airspace at the chino, ca, airport without clearance from chino tower. After completing the turn and subsequent vectors, we landed on runway 26R without incident.
