Icelandic volcano and computer modeling

Several test flights in Europe reveal no damage to jet aircraft despite the risks European authorities are claiming. So how did the authorities determine the planes could be damaged? Computer models. From the Telegraph:

Lufthansa also flew 10 aircraft from Munich to Frankfurt on Saturday with the blessing of the safety authorities.

A spokesman said: “We found no damage to the engines, fuselage or cockpit windows. This is why we are urging the aviation authorities to run more test flights rather than relying on computer models.”

Do you know what other grave threat facing humanity is being pushed by computer models? Global Cooling Global Warming Climate Change.
