MAYDAY MAYDAY MAYDAY
I'm a bit concerned that so many apparently professional military aircrew just don't give a damn about internationally accredited procedures (which I guess they must have understood to gain their qualifications). What other procedures are they ignoring because it's more convenient to do so or because that's what everyone does? If US ATC staff don't understand international procedures they aren't being trained in accordance with international standards. The procedures are there for very good reason, they should be ingrained in anyone with a TX switch.
I can only marvel at what it took to get that C130 back on the ground and many say WTF nobody died. Yeah but a Mayday call might have made it easier for everyone else (assuming everyone else understand what a Mayday call means, which it seems isn't a given).
