Hi again, I downloaded the latest British Airways Worldwide Timetable, good for dates from July 1st, 2003 to October 25th, 2003, and have confirmed that the Concorde is scheduled to leave nightly at 6:30pm out of Heathrow for JFK at 18:30 out of terminal 4 -- flight BA001. (At least for the next 17 days). The arrival time is 17:25 at JFK, which is 3 hours 55 minutes later. The website reports that the flight time is actually only 3 1/2 hours, so there's 25 minutes of fluff in the schedule. Splitting the fluff equally between Heathrow and JFK means an ~18:42:30 take off.
Concorde's takeoff speed in 250 mph, and Heathrow is ~180 miles east of southern Wales. If they flew a straight line and averaged 450 mph over that distance, they'd be over Porthcawl in 24 minutes. (Given that they have to fly subsonic over land, I doubt they can average much more than 450 mph over the first 24 minutes of flight). So: 18:30 + 00:12:30 + 00:24 = 17:06:30 The Pencoed picture was supposedly taken around 17:13, when the object producing the contrail is already well out over the water. I don't know about you, but I'd say the circumstantial evidence is pretty strong. (One might well ask, "If that's NOT the Concorde's contrail, where ~is~ the Concorde's contrail, since it ought to be in the same field of view?!") Isn't it nice when all the facts come together to form a coherent, logical, simple explanation? --Rob ______________________________________________ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
