I don't think he is. A few weeks ago at night the BO (-135) kept extending the boom for "ready for contact" so I kept moving in from pre-contact (sorry, astern...gay), then he'd get on the radio and tell me to return to pre-contact. This happened with everyone in the flight at least twice. WTF dude! Then my favorite radio pile-on is, "Viper 3, cleared to contact." No fucking shit, I just finished and this is EMCON 2. And yes, I got asked for my 5 digit tail number over IC at night with my lineup card buried at the bottom of a stack of mission materials. Unfortunately I have seen this act on many occassions, so I think 3 holer is right on...a lot of tanker crews either have no idea what EMCON 2 means or they're just sloppy and don't give a shit.
That said, thanks to all the awesome tanker crews I have worked with who followed EMCON 2 and actually did things to help us out (i.e. get out of the wx without me having to ask, being flexible with dragging us to where I wanted...yes, I've had crews refuse to leave the track, even though its in the middle of our airspace). Don't want to make it sound like all my tanking experience has been bad, because it has not.
