Part of the issue is that the government did not anticipate the steep increase in airline travel, so the TSA is now rushing to get new screeners on the line.
Enhanced security measures since then, combined with a rise in airline travel due to the improving economy and low oil prices, have resulted in long waits at major airports such as Chicago's O'Hare International.
Paragliding, bungee jumping, surfing, river rafting, shark cage diving, hot air balloons, hiking, cycling, wine tasting, whatever this guy's doing, does that not look like fun to you, Michelle?
Since NASA retired its space shuttle program in 2011, the U.S. has paid for astronauts to hitch a ride on Russia's Soyuz spacecraft to get to the ISS. Space X could get them there on American vehicles once again.
They'll be launching in a newly designed spacecraft for the first time since 1981 and they'll be launching aboard a SpaceX capsule for the first time ever.
Meanwhile, without testing all we can do is large-scale mitigation efforts like getting rid of crowds, telling people not to fly, other things like that.
