Anyone who has seen the pictures of the MAn 737 won't need any convincing that if you ave a fire you put the fire down wind. Simple, like most SOPs they are there for a reason, thats so we can learn from past experiences and not have to live through them. I've worked for a few airlines and all have had the same philosophy, thats how you train thats how you fly.
Say that the Man 737 was a one off and shouldn't be used to formulate a policy is sheer folly.
