what could be your hypothesis regarding the crash of air france's A330? if im not mistaken, the plane was just 4 years old..that means the plane is still structurally durable and that the on board equipments are still of good condition...with the report that the plane was hit by lightning, i couldnt actually consider that as a good basis since planes nowadays and even older ones are built to withstand a lightning strike without or with slight damage only...
