Ok, I will, you sad old git. Perhaps in your haste to put $hit on me, you missed the body of my post, which was an explanation for the guy. It probably hasn't occurred to you, but if you look thru the posters history, he is more likely a software developer writing code for a video game or an add-on for Flightsim (or some such thing).
Do you seriously think that a person in the position of writing regulations or instructing in a college (as he/she has variously claimed) would have the knowledge base demonstrated here? Would seek answers on Pprune? Basic vectoring questions etc? Exactly how stupid are you? This is the internet, ffs, people can make all sorts of claims. I would prefer he just came out and told the truth. You, however, may continue to post your stupidity for all the world to see.
Welliewanger is correct. Given the disposition of the a/c in that diagram, if you turn the northbound left and the westbound right I don't believe the apex of the turns would occur until after they had passed (the first time). They would then be pointing at each other again (if they survived the first pass). Very high performance a/c such as fighters might be able to make the turns the poster suggests. Not airliners.
