Narrative:
While on a training flight out of San Antonio, the instructor told the student to execute 'a no flap landing due to a simulated hydraulic pump failure.

The instructor stated that the landing gear could not be extended until landing was assured, but he forgot to lower the gear afterwards. The Metro III plane landed wheels up and slid off the side of the runway.
