Those ones actually pivot. I don't know if it was on all B-52s, and I don't think it's on any other planes.

I've sat through a few crosswind landings and they're pretty unsettling. In something the size of a B-52 (and with the load it generally carries), playing with the landing gear makes a lot of sense.

Just that you seem to prefer to keep a low profile.

Since all SAC (or whoever they are nowadays) primary runway faced pretty much due north, the B52 gear skews up to 6 degrees which is why they are on centerline, the wingtips have retracting swivel gear. G and H models are essentially upgraded rebuilt D models.

Not sure because I can't find my whiz-wheel, but that skew is good for about 50 mph crosswind

I'm willing to learn something here but I'm going to need some guidance.

Is the lift of the Dream created by the attached airflow over the top of the profile or because the design of the underside creates more pressure on the underside than is created on the top (underside pressure >topside pressure. Lift created by a specific design.) or us the lift created by the basic shape resembling an airfoil and adds as such (Bernoulii ?) because it is positioned high enough off the road that it acts as a "wing" (not a specific underside design to create lift, but placement of a basic design in relation to the road to create lift)

The airflow is not attached, and the lift is Bernoulli caused. Others will find nits and pick them, but this is simple and succinct

It was predicated on the centerline main gear and relatively light outrigger gear. *That* was predicated by the high mounted wing position, big mains would be huge and heavy outboard on those wings that are so high in the air.
Note that huge airliners have substantial outboard main gear that can take the abuse of a significantly dropped wing to keep tracking centerline in a forward slip.
The B-52's little outrigger gear would simply break off if you did that to make that transition from crabbing to cross-controlled forward slip to landing. Heck, the wing would break if it did not!

I thought unattached airflow (flow separation?) was more turbulent and caused more drag. If the Dream is low drag then wouldn't it have more attached air and less turbulent air moving around the body?
