I can only assume that they are flying very low. If those flights can do it, why can't some of the other flights go? Bod

If you where to set a limit of say 20,00 feet who would decide which airlines could use it, there would be some very pissed of operators who are be left out. Better that there is a blanket ban for commercial airlines and leave the low levels used by the armed services if an emergency should arrive, commercials travel at around 300-350, Tornado's at warp speed are not a good mix. -- Corporal Jones "Don't panic don't panic" Life will go on albeit somewhat reduced

In any event it doesn't matter. It's not a risk that can be taken. Derek |
