Nice link on the
407 here.
Don't know about the T-33 redo, but I read in AIAA a month or two ago that Blackwater has Super Tucanos on loan with the Air Force who likes them far too much. Tucanos may be groovy but Wichita needs more jobs and already has several low and slow attack airplanes ready to go. Incidentally, Blackwater calls themselves DKWSATI these days... don't know who shot all those Iraqis.
