Russian and NATO war planes launched their first ever joint anti-terror exercise on Tuesday, coming together in an attempt to prevent incidents like 9/11, a Polish official said. The jets are participating in the four-day Russia-NATO “Vigilant Skies 2011” exercise, which started on Monday and involved flights over the Black Sea and Poland. According to a statement issued by NATO, the aim of this event is to “improve air safety for the thousands of passengers using international flights between NATO airspace and Russian airspace each day.”
