It says fumes not smoke! Oh that's ok then, how I'm happy your not commanding my flight anytime soon. Don't worry folks, its only fumes in the cabin.
As for tandem - I would agree BA's current safety record is becomming quite a yawn. Must be terribly boring to have this repeated 3 times in 1 week. Instead of yawning, you would hope those responsible for safety at BA would wake up and do something.
Artificial horizon - there is no need for me to bring British Airways into disrepute (and not my intention,just reporting a growing adverse safety trend). British Airways have become expert at the art of disrepute all on their own.
