Well I think this would be a damn good thing. Smoking is frankly disgusting, and BA is obviously taking the moral lead in this case. Why should smokers be allowed on the TPS, eh? In the event of a depressurisation they're unnecessarily endangering the lives of their passengers and colleagues. If they were really committed to being an airline pilot they'd be happy to quit on joining anyway.
What *really* annoys me though is these "social" smokers that only have a ciggy when they go out of an evening. They don't even have the excuse that they're addicted! At least some old hack on 40-a-day can claim he doesn't have the willpower or moral fibre to stand up to his problem, but these wet-behind-the-ears smoking wannabes can't even say that. Pathetic.
Hooray for BA, I say.
