Scenario: STN. A/C lined up and given takeoff clearance. He is tardy and is taking a long time. (we've heard stories about no cabin secure etc.) ATC says to a/c on finals, "continue, expect late landing clearance." All seems fine. ATC gets nervous and at 200' calls a G/A just as ground traffic starts to roll. The GA route stops at 3000' and is exactly the same as the SID which stops at 4000'.
What would you do? is the question on the ATC exam paper.
