siznaudin Posted August 31, 2009 Share Posted August 31, 2009 The SR-71 set and still holds the "Speed Over a Recognized Course" record for flying from New York to London in 1 hour 54 minutes and 56.4 seconds, on 1 September 1974 while flown by U.S. Air Force Pilot Maj. James V. Sullivan and Maj. Noel F. Widdifield, reconnaissance system officer. This represents an average speed of about Mach 2.68, including decelleration for in-flight refueling. Peak speeds during this flight were probably closer to the declassified top speed of Mach 3.2+. (For comparison, the best commercial Concorde flight time was 2 hours 52 minutes, and the Boeing 747 averages 6 hours 15 minutes.) Link to comment Share on other sites More sharing options...
sixtiesrelic Posted August 31, 2009 Share Posted August 31, 2009 Not really value for money is it... they didn't even have time for sandwiches and a bottle of drink. Checklists all the way. Link to comment Share on other sites More sharing options...
