'Speed Pants'...

Sounds reasonable, yes, but they DO look cool!
Wouldn't want the complication of an extra (belden?) cable, though.
If some clever one could find a way to maken them open
automagically, now that would be great!

How about using ram pressure to keep them closed, via a pneumatic cylinder,
then when ram pressure is less, like slowing for landings, they open up,
probably spring assisted.

You could also use something similar to a Piper stall vane, where at some
predetermined AOA, the vane operates a switch that opens the doors.
Alternately, you could plumb a pressure sensitive switch into the
pitot/static line.

You'd need to have the thing rigged to fail in the "open" position, or an
electrical glitch could result in a landing that went crunch, instead of
chirp (or bounce, bounce, thud.)

If one were to open and one remain closed ...well now:

Let's see, if you landed on one wheel you'd maybe swing around to the closed
pant side. Unless you tapped the brakes, then I suppose you'd swing (pivot!)
around back to the free wheel side.

Talk about some nasty differential steering.

I'm not sure you would even feel it if you landed with one or both doors
closed.

True enough, but I am also not sure that you would not end up on your nose
or in a nasty ground loop. IMHO the added expense, complexity, and risk is not
worth the presumed 2 mph speed gain.

I heard that leaving them closed for landing simply scrapes through the doors and the pilot didn't even notice. I don't
see any costs quoted, but I imagine they would cot a little more than simple pants.

I like the auto actuating ideas...
