Narrative:

B757 checked in for runway 28R, visual approach. Tower changed runway assignment to runway 28L and cleared aircraft to land. Lear was put into position runway 28R, intersection east (midfield) after preceding arrival rolled through. When tower cleared the lear for takeoff, he noticed B757 on short final runway 28R and sent traffic around. This situation should have been observed by the B757 cockpit crew. It was not obvious to tower.
