But the larger point here is that we have always had a constrained and stressed NAS. Year after year, administration after administration, we have simply fallen further behind in upgrading and enhancing it due to money and politics. The shutdown is just bringing it back into the spotlight again.

The FAA has a "Playbook" that contains pre-constructed constraint and re-route orders they employ to handle this stuff. For example, yesterday they deployed the "PHLYER WEST" play for flight departing PHL, which caps them at 8000' initially. www.fly.faa.gov/playbook/pla...

Capping / tunneling simply are using different altitudes to get under or over a flow constrained area of airspace. Capping = stay below. Tunneling = stay above and below. It’s all relative to a flights route and where the flow constraint is.

Actually happens a lot in the NE corridor, and has been used for years. Known as “tunneling”. Not just a small plane thing. It’s literally an airspace saturation thing. A small plane takes up the same airspace and ATC resource as a big one.

Being reported by the org that sold out to MAGA to the point of publishing tabloid-esque smear stories about James Talarico’s Instagram follows yesterday. Um ok.

Oh FFS. GOP is gonna pick the most MAGA person they can, because that’s what Trump and his propaganda team will want. So it’s not gonna be Demuth, that’s for sure.

But agreed with your OP.
