Re: A-10 reduction to begin soon.

CAS, done by any plane, requires a somewhat permissive environment. The A-10 was designed with missiles in mind—the engines in particular are of a type that minimizes heat signature and then the efflux is shielded by the twin rudders. It was fairly hard to get an IR lock-on with the older MANPADS. ...

Typically higher wing loading flies faster, with many exceptions and such. In particular, lower wing loading lets you fly in thinner air, which helps you go faster.
