Airplanes Flying Through Desert/volcano Storms

Wed Mar 31, 2004 3:53 am

I believe BA had an incident in the 80's between Singapore and Perth where all of the engines of the 747 had fallen out.

Does anyone know about similar incidents?
In which Parts of the world does this happen frequently?

It is true that this happened to BA on 24 Jun 1982. The 747-236B G-BDXH flew through the plume of a volcano eruption.

It takes quite a bit of ash and smoke to actually shut down the engines, so this plane was at once supremely unlucky, and then supremely lucky to recover. The plane was a glider from FL370 down to FL130 and still only got 3 engines to stay lit.

This also happened to a KLM 744 on 1989.

This is in no way frequent, but I guess there is some theoretical potential wherever there are active volcanoes.

Most active and semi active volcanoes are in a ring along the coasts around the Pacific Ocean and islands within that ring (including Hawaii). Better detecting is being developed on site and from satellite sources to locate and indetify possible active volcano sites so the risk of the 2 noted events is probably reduced in the future, although not completely negated. Flights can then be re-routed to detour the high risk areas.
