Of course, you can only fly safe if the other guy does too. While happily SLOP'ing in SE Asia, another aircraft went precisely over the top of us.
We asked how come he was out there? The answer was "If every body is flying 1.0nm right, I'll fly 1.nm left and keep out of their way." This guy was a Captain for a major flag carrier!!
Yep, stay safe out there!!
G'day
