When Congress tried to overrule the Air Force on CSAR-X, it set a bad precedent. In essence, by dragging a lot of politics into the mix, they have delayed that program for a while.
Now, KC-X is facing a similar delay, this time, rather than trying to stick it to Boeing, Congress is going to earmark the contract to Boeing. Now, I will not call this a pork-barrel situation, as CAGW did (CAGW in the past has come out for going back to oil-fueled carriers, killing the V-22,and has called the C-130J pork, so take their national-security recommendations with the appropriate level of salt).
The fact is that there are some people have about the Northrop Grumman entry. They are questions that deserve answers.
