Flyboy 007.....
Perhaps you've taken leave of your senses, taking off in freezing fog is no problem with the correct type of fluid, at the correct concerntration....in fact its no bother at all, I did it in Chicago a few months ago..and lived to tell the tail
This is all wrong btw, the RNZAF should stick to inflating their egos' and being frustrated they don't have anymore fastjets...they should leave flying airliners to the professionals IMHO
