Write your reply.

assistant: <- Charles Mielke talked to Mark Foster, and Look What Happened! ->
 Turns out I had it a little backward - see the previous message...
 Heheh i'll point out now that I'm actually a licensed Amateur Radio
 Operator, and a military enthusiast besides so yeah i'm familiar ;)
 <grin>
 Its the same with us Hams...
 Heheh My father used to do a bit of that.  Hes ex- Royal New Zealand
 Air Force, (not a pilot however).
 I gather you're ex-service?  Can I ask which, and doing what?
 Merging Plots is the term where the individual blips on a radar screen
 are so close you cant tell them apart.. usually during close-formation
 flying on long range radar.
 Hmmmm I'll quote something here if I can find it.
 (Taken from 'Chains of Command' by Dale Brown (an ex- F-111 Nav, USAF))
 The controllers mike opened, there was a short hesitant silence; then:
 'Ah, roger, Zero-One Flight.  Can you accept MARSA at this time?' MARSA
 stood for Military Accepts Responsiblity for Separation of Aircraft,
 and it legally allowed military flights to fly in close proximity to
 one another.
 'Thunder Zero-One accepts MARSA with Zero-Two.'
 -- etc.  This is during an exercise where the flight of 4 F-111G's are
 airborne with live rounds, and allovasudden Russia Bombs the Ukraine
 and US forces go to DEFCON 3... ficticios I know, but the theory is
 secure in that theyd disperse their aircraft incase of nukes...EMP
 damage and all.
 Yeah, well, I'd understand it would be horizontal as well as vertical
 spacing :)
 Thanks fro the input, its much obliged...
