Row one of this company's 1900 has no window (where the baggage locker normally is on most others), row two also has no windows do due reinforcing for the ice off the props which i thought was made of kevlar(?), eitherway I would have thought it would be strong enough to stop part of the blade coming inside if the situation arose.
As sequ mentions, feathering the props could have some cost benifit but the consequences of getting it wrong far outweigh any potential benefits. Especially so for the national flag carrier, its probley better off making the insurance claim than putting the punters at undue risk.
