I can think of one marked improvement: one costs the taxpayers nothing, and the other does.
The NWC budget is chump change in the federal budget. And unlike many parts of the fedgov, the NWC actually delivers something of considerable value for the tax dollars spent.
As Nauti Nurse noted, do you think a private company would arrange to fly aircraft into a Cat 5 hurricane for critical forecast info?
Unlike much of the fedgov, this ain't broken.
