Paul, that's exactly what I was thinking. In watching the videos, it
looked like the aileron effectiveness was very poor, so if a wing
started rolling, it just kept going. That combined with the low tip
clearance meant that the airplane looked very prone to easy ground
looping. If the airplane had better roll stability, I think it would
be easier to land.

In the flying article, they comment that in order to save weight, the
airplane has un-boosted controls. The plane really only lightens up in
control forces at it's design mission. The rest of the time, it takes
a lot of strength and force to move them. Can't imagine that's very
easy after flying for a long mission, now I have to do a strength
workout just to land.

IIRC, the only 'boost' control was the vernier control on the engine
exhaust nozzle. Controllable to within 1.5deg F.
