Hehe ..... good point.
In truth, at least the F-117 still seems to possess the characteristics of an airfoil...albeit, a singular foil (like a flying wing).
A Colonial Viper, at least to me (and yes I am FAR from an aerodynamics expert) just looks a bit too.....blocky, and has too small of a wingspan to begin with.
But, like I said, we did have some test aircraft (IIRC) that had very stubby wingspans....but, they still had airfoil characteristics.
Again, I am far from an aerodynamics expert, so, as with all things, take my opinion with a grain of salt....or just take the whole durned shaker.
