Are the Zoomies still using 135's? They were using those way back in the '60's. Still, Air Farce is certainly a better option than joining the Army.

Mind your manners, ground pounder.
Yes, the 135 is still in service.
Not that you trench huggers could tell the difference.
Yes, but they have been re-engined. The active force KC-135s, and few other varients, with big fan engines (CFM56/F-108), newly built. The Reserve and Guard birds got take off JT3Ds from airliners. TF-33s in miltary designation. They are Lower bypass turbo fans, but still better than the J-57, turbojets they sported originally. The AWACS,which is not a -135 airframe, also uses TF-33s, at least in US service. Other nations have up engined to high bypass turbofans, for better performance/higher altitude flight, and for much increased fuel economy. I don't know which engines the RC varients use. Some of each is possible. According to the Air Force Fact Sheet they've gotten the F-108s.
