WE are in fact in charge of the boarding of passengers onto OUR airliners.
As we fucking well should be.
If some "sniffer" failed to work or if it didn't even exist at the boarding location, that's bad enough, but understandable in isolation.
What is NOT all that understandable is how or why a fucker ON one of our watch lists, coming from a God-foresaken cesspool like Yemen, without a passport and with no fucking luggage for a long overseas flight TO the United States who has been identified by his own FATHER to OUR people is allowed to get onto a U.S. passenger jet bound for the U.S. in the first fucking place.
How can these kind of things be prevented? A little bit of fucking common sense would have gone a mighty long way.
OK counselor...freshen me up. By what treaty or law do American companies call the shots in foreign countries? As far as I know there are no airlines owned by our government. I as a pilot know a few things but not being a commercial pilot I don't know the authority of which you speak. One thing the public may not know is that all air traffic control world wide is spoken in english.
I have already provided one such link.
I am tired of doing other folks' homework.
Since the fucking flights are coming into the USA, the Federal Government by laws (and rules and regulations promulgated pursuant to those laws) DOES tell the airlines what they must do.
The airlines do not need to be "owned" by the Federal Government to be obliged to abide by such laws and rules and regulations.
For example, here's an interesting tidbit of information which is (itself) more or less directly responsive to your question:
