If the incident is confirmed, it would mark the first time one of NATO’s most important strategic air transport hubs has been directly affected. The SALIS Agreement on Strategic Air TransportSALIS is a multinational support partnership among nine NATO member states that provides participating nations with guaranteed access to strategic air transport capabilities. These Antonovs transport everything that does not fit into smaller transport aircraft such as the A400M. Leipzig Airport has been one of the operational bases for NATO’s Antonov aircraft since the launch of SALIS program in 2006. But yesterday’s incident shows that the security of this extremely important military transport hub is, at the very least, at risk.
