For those that are interested in the last overrun down this dropoff, look at...
http://www.avsaf.org/reports/CANADA/...Canada_189.pdf
The DC-9 was taking off with slats extende but zero flap with a high rotation speed. A main wheel tire tread came off at high speed but below V1 leading to vibration, along with a main gear unsafe light from tire debris and a decrease in engine power due to tire ingestion. After rejecting the takeoff, not nearly enough braking was used possibly due to distraction from difficulty in spoiler operation and the aircraft went over the embankment but at a high enough speed to actually get airborne leading to high vertical G-load on impact. The report only briefly discusses the overrun area staing that it was within accepted international standards.
