"US Steps Up Security for World Airlines"

"That's right, Euro-Pardners, either get a Texas Ranger on all your international flights to America or plan on air-to-air refueling on your way to Canada ... well off the coast," was one of the commentaroes after the Homeland Security Department called for marshalls in foreign plans.

(An interesting aside: this was published 24 hours earlier already in European media.)

And some kind US-papers mention - see google news-search - that Mexico and the UK already announced they will put undercover armed police on some flights.

(Another aside: just wondering, why it isn't mentioned that this is done since two years on German airlines?)

Britain, it seems, doesn't like this idea very much:
"Pilots and airlines are worried that arms given to flight staff might end up being used against guards and passengers."
Fears mar case for guards in the sky
