One of our normal runways at MIA was 13,000 ft long taking off to the west. Our airline required us at V1 to continue the takeoff. A friend of mine took off and had a thrust reverser deploy at V1 taking off to the east in a 727. He managed to get it back and land but aborting was the safest procedure. He followed company policy and returned for landing. All was sucessful but sometimes staying on the ground is the best answer. Remember the DC10 at Chicago crash? Sometimes company procedures will kill you.
