This may have nothing to do with jihad, of course. There are no doubt other groups that would like to get hold of an anti-aircraft missile. And there is also [1] this story from Los Angeles: "Pilot Reports 'Missile' Fired at Jetliner Near LAX."

Whether or not these two incidents are jihad-related, they could indicate that the jihadist dream of wreaking such mayhem in the United States could become a reality, and not too long from now.

From [2] AP, with thanks to Sr. Soph:

Police pulled over a tractor-trailer loaded with anti-aircraft missiles on an Ontario highway Friday.

Several police cruisers were needed to pull over the vehicle on Friday as it traveled westbound on Highway 407, near Toronto and its international airport. The Canadian Army was investigating the incident.
