I'm as clever as any PHD, if not more so
And we didn't get all the information that your PHD friend seemed to get. Headings, speed, passing FLs and distance didnt give us relative position to each other.
And I imagine your PHD friend has more more time to scribble on paper and stuff, us lot are watching radar screens and pointy flying things out the window.
No offence Singaporecanc.
Traaaaaaaaaaaaaaaaaaaa.
