US SECURITY is being stepped up to unimaginable levels with the latest dictate that visas are now being required for transit passengers from other than the 26 nations that America deems acceptable. What happens if such an alien turns up at a States-side airport is open to reflection as if that person is returned to the boarding airport he or she will still be airside whilst waiting for the next flight. He could be outbound quicker by catching the original connection. And passengers should be warned that new instructions from the Department of Homeland Security asks airport authorities to pay special attention to cameras, flash devices and laptop computers. Have patience. Vancouver Airport, a very popular gateway to the US last week suffered from a possible security risk severely delaying flights. http://www.dhs.gov
