It's certainly more fun, though, to listen to all the alphabet groups with
a vested interest.

You don't think those links are written by someone with a vested interest
or bias of some sort? Why else would the first article start with citing
the problem of congested airports but call that an ATC issue? That's
misdirection; simple literary dishonesty.

The second simply says essentially "there's evidence that we're right" w/o
citing any.

The third speaks to a funding problem. Yet the GAO disagrees, according
to testimony by Gerald Dillingham. Calvin Scovel of the DOT agrees with
that testimony.

The forth, in part 3, commits the same act (though admittedly it is merely
citing FAA staffers with their own biases and vested interests).

More, the fact that the airlines are apparently able to exploit this
process to try to achieve yet another tax break (despite the claimed
issue being an FAA cash shortfall) makes it clear that the process is
biased and therefore flawed (and pretty much congressional business as
usual).
