The NTSB recommendations are a bunch of horse s**t. I used to have respect for the NTSB, but after listening to the woman who heads it, I fear that she's cut from the same cloth as Administrator Garvey. If that crap about not agressively using rudder is the best they can come up with, then they're better off keeping their mouth shut until they find some that they can PROVE.
I've had a hardover rudder on a KC-135 so bad it bounced my head off the side window. Damage? NONE.
I've also flown MANY times minimum interval takeoffs (MITO)during the cold war. 12 secs behind multiple aircraft in wake turbulence you only read about, and you know what?? It's not a big deal. Easily handled by both pilot and aircraft.
