Approaching 10 years flying boxes, and more glad avoiding with every passing day....

I used to brief this more on OPSEC than anything else, but when flying a D model Eagle (2 seater) I would tell the other person "never say anything on the intercom you would not say on the radio. And never say anything on the radio you wouldn't want to hear on CNN...".

While it isn't tactics we are protecting now, the same ROE applies to cockpit conversations. Save your inner secrets for the bar....
