Maybe the manufacturer was keen to avoid another write-off as that could affect future insurance premiums for all hulls...
Well if it did have an affect that would hardly be fair - the 777 has been extremely good for many years now.
Arguably even the incident involving BA at Heathrow shows that given half a chance the 777 will keep everyone alive and mostly unharmed in the most trying of circumstances. That should have a positive affect in premiums.
