Vmc is the minimum airspeed to maintain directional control of an aircraft that's lost one of it's engines. The rudder needs a certain amount of airflow to maintain directional control, and the rudder is greatly needed when an engine fails because the operating engine produces asymmetrical thrust and lift, which causes the aircraft to roll and yaw into the dead engine. If the adverse roll and yaw aren't countered with opposite rudder, then the increased drag slows the plane down even further and if the wings stall at an airspeed equal or above Vmc, you're really in trouble. Most twin-engines don't recover well or at all from flat power-on spins. We had to demostrate Vmc recognition and recovery during my multi training and it always made me a little nervous.
An instructor and some students were killed the previous year doing the manuever because they miscalcuated Vmc, which varies with weight and atmospheric conditions. It was too low, below the aircraft's stall speed, so when they demonstrated Vmc, they stalled at the same time and spun the plane into the ground. Due to the fact that four people and one of the student's dog was in the plane, the spin was fairly flat and could not be recovered through normal spin recovery procedures.
As a result of the accident, the school said that all Vmc demos would only be conducted with two people in an aircraft, not four.
