SK686 Why Was This Not Survivable?

Fri Dec 12, 2003 6:44 am

Just having a look on AirDisaster.com and reading the story on SK 686 crashing in Milan, it is hard to believe there were no survivors given that so much of the aircraft remained intact. I always thought the biggest threat of an incident while on the ground was fire, but it looks to be largely unaffected. Can anyone tell me why?

I have often wondered this myself. The plane was severely damaged, but it's not completely disintegrated as the airframes in most nonsurvivable crashes are. I too find it hard to believe nobody was able to escape. Perhaps the impact forces were too great, although again, that doesn't seem consistent with so much of the plane remaining intact.

According to the preliminary report of the Italian authorities, the MD 87 hit the Cessna at 146kts just after takeoff, hit the end of the runway, turned approximately 45% sideways and hit a massive concrete structure aka baggage handling building (which was as long as the MD 87 turned at 45%). The report estimates impact speed at 139kts, causing two of the concrete support pillars to buckle in. Add a fire fueled by 10tons of fuel.

Guess the deceleration forces (139 kts to standstill within a couple of metres...) were too great.
