Not trying to put you down but have lots of experience with 1000 mph + rates of closure in heavy iron. That's over 16 miles a minute and about 1500 feet per second. At one eye blink per second that's about 7500 feet for 5 seconds. That's almost a mile and a half travel in the 5 seconds. If it takes the brain 2 seconds to process information a bird can be pretty dam close before one can try to recognize. Unless one is forewarned by center, aircrew may or may not see closing traffic unless pulling a con. Trans ocean traffic is very boring (as you know being in the business) and no one crew member is tasked and sits there with an eye ball covering the forward quadrant during the long cruise portion of flight. In fact some airlines allow one pilot to nap during fight so he will be sharp at destination I'm told. They found some pilots were doing this due to late night and boredom so they made it legal ![]() they gave us Phenobarb (sp) prior to landing. All of this discussion after the fact is media garbage. Bird with President aboard does NOT have to use the Call Sign AF!. In Stealth mode it can be called anything. I'm just surprised that some media type didn't let the cat out of the bag unless they took all the cell phones away and gave everyone a pat down and only let them use the birds com system after they had departed Iraq and were in International airspace. No matter what the nay sayer's say, good trip and a boost for those in Iraq even if he was pretty closely monitored and protected. He did go in harms way and a brace of mortars could have caused a lot of casualties and put the media in a frenzy. Big John New subject. Where can I get the positive and negative G limits of commercial birds, 747, 757, 767, etc? I want operational limits not ultimate. Have looked on Internet and not found so far.

Didn't they a few years ago reduce vertical separation from 2K to 1K if certain (new accurate alt measuring) equipment was on board the aircraft to increase (double) traffic density on the overseas routes? Yes, it's called RVSM = Reduced Verticle Seperation Minimums If flight was direct from way point to way point then I doubt if the birds came within visual range??? Would be an odd throw of the dice. Huh? With all do respect, I do this for a living and there are "birds" somewhere in the Flight Levels that come within visual range of each other (both same and opposite direction) every minuite of every day. We are often able to visually identify company paint schemes and aircraft types (again both same and opposite direction) all the time. There is nothing odd about it at all. Plus, with the 1K RVSM sep that you talk about above, it would be even easier. That said, I can postulate a situation where two birds with a few thousand feet vertical clearance going the same direction on the same route and with different cruising speeds, slowly pass each other and BA be able to recognize the distinctive paint job on AF1. This in day light of course. In the real world "birds" don't just flash past each other in the FL's in the blink of an eye. Even if opposite direction you usually have several seconds of good visual (weather conditions permiting, of course) opportunity for an identification. Tale has a lot of characteristics of a good bar story ... I disagree. To those of us in the trenches (er, Flight Levels) it has the characteristics of an entirley plausable event that happens every day. Good show George. Agreed. Regards, Mish |

It's been widely reported in both broadcast and print media and has been confirmed through gov't sources. Knight Ridder Newspapers even printed a quote from the AF1 captain. No one is trying to keep it a secret. Pilots Didn't Radio Air Force One, Airline Says WASHINGTON POST Page A03 "We have spoken to the British Airways captains who were in the area at the time and neither made comments to Air Force One nor did they hear any other aircraft make the statement over the radio," Verrier said. http://www.washingtonpost.com/wp-dyn...-2003Dec1.html |

![]() A tall tale. If another aircraft really had eyeballed "AF1" and called up as stated, the AF1 pilot would have just ignored the call. Also very unlikely that any other aircraft would be able to get into visual range -- AF1 would have deviated to maintain greater separation. They do have better than average radar, you know. :- Thats what I thought. Also, I just realized how stupid it sounds saying that I assume TFRs are in place wherever AF1 goes, but I do assume there is some sort of TFRthingamajig overseas. |

Not to mention, of course, that I have yet to see a TFR that follows the
airplane enroute... Besides shutting down half the country's airspace, it would also be a big-time security breach... "2/1234 TX.. FLIGHT RESTRICTIONS SOUTHEAST USA DECEMBER 3, 2003 LOCAL.

Of course they do exactly this for a presidential motorcade. all the best -- Dan Ford email: see the Warbird's Forum at www.warbirdforum.com and the Piper Cub Forum at www.pipercubforum.com |

Of course they do exactly this for a presidential motorcade. Perhaps, but the square-footage is much smaller. A presidential motorcade should only close down a major city or state. The flight plan that I outlined in my TFR went from Waco, TX to Washington National, closing the entire southern half of the US... Not to mention that a terrorist in a Cessna 172 would have more trouble hitting AF1 in flight and has a much better chance of hitting the President's Limo with a Water Bomb! |

Judah, using unbridled hyperbole to try to make a point rarely enhances a discussion. AF1 movement TFRs do NOT shut down "...the entire southern half of the US...", as you twice posited. As a general rule, they proscribe a particular route, but then only "...unless otherwise authorized by ATC...". X miles before and after passage, other traffic will be allowed to cross paths. You do, in fact, have a TFR that follows the aircraft (as long as everything runs smoothly); a moving bubble of airspace kept clear for the passage of AF1. |

![]() How did he see AF1 with the TFR in place, I assume they are in effect wherever AF1 goes in the world. I don't think the US has that much power that they can get other nations to play the silly airspace games we go through here. Margy |
