Ringwayman:
So the Speedbirds you quote didn't divert due fog, they actuslly diverted due FUEL, which is a different point to that made by R308R.
Angel Fish/Cake or whatever:
I suggest YOU find out what the term "R308R" actually means, and when you find out, reconsider your slagging off of the eponymous PPRuNer.
PS: I prefer IBI67/240/4 myself!
