At the Aero Club of America Meet on 26 September 1911, at the Nassau Boulevard Aerodrome on Long Island, New York, Lieutenant Thomas DeWitt Milling set a world endurance record of 1 hour, 54 minutes, 42.6 seconds with two passengers, for which he was awarded the Rodman Wanamaker Endurance Trophy.
The trophy is on display at the National Museum of the United States Air Force.

Mr. Swopes, do you have any further information concerning this event? “26 September 1958, a USAF B-52D set a world speed record of 561mph over a 10,000km (5,400 nm) closed circuit without a payload. The same day, another B-52D established a world speed record of 598mph over a 5,000km (2,700 nm) closed circuit without a payload. “
Good morning, James. I don’t, but let me look into it. I’ll get back to you. Thanks. —Bryan
James, the FAI does list two records for a B-52D set on 26 September 1958. #8498 is for speed over a closed 10,000 kilometer circuit without payload, Victor L. Sandacz and Kenneth G. Wolf, 902.369 km/h (560.705 m.p.h.) mph); #8499 is for speed over a closed 5,000 kilometer circuit without payload, Cholett Griswold and E.V. Godfrey, 961.867 km/h (597.676 m.p.h.). The aircraft is/are not identified, so one B-52 could have set both records, or they could be different B-52s. Further research will be necessary to see if I can find enough information to write a post. Thanks for the question.—Bryan
