24 June 1993: In compliance with an arms control treaty between the United States and the Soviet Union, the Aerospace Maintenance and Regeneration Center (AMARC) at Davis-Monthan Air Force Base, Tucson, Arizona, immediately began the destruction of 363 Boeing B-52 Stratofortress strategic bombers.
22 May 1937: Earhart’s Lockheed Electra 10E Special, NR16020 was repaired at Tucson, Arizona after its left engine, a Pratt & Whitney Wasp S3H1 nine-cylinder radial, caught fire while restarting after a fuel stop the previous day. Amelia Earhart and her Navigator, Fred Noonan, and two passengers, flew to New Orleans, Louisiana, on the 22nd.
Although she was actually on the third leg of her second around-the-world-flight attempt, no public announcement had yet been made.

AMELIA ‘JUST FLYING ANYWHERE,’ SHE SAYS
(United Press by Radio)
TUCSON, Ariz., May 22—Amelia Earhart Putnam took off for El Paso, Tex., today in her newly repaired Lockheed Electra plane.
She said she was “just flying anywhere to check the plane and see that everything is working properly.”
“It’s just like new now,” she asserted. “I’d like to put at least 50 hours flying time on it before the big flight.”
The “big flight” will be her second attempt to fly around the world along an equatorial route. She hopes to take off soon after June 1, weather permitting, with Honolulu her firsst stop.
Her plane was smashed at Luke Field in her first attempt.
“The next morning at Tucson a dense sandstorm blocked our way, but despite it we took off, leap-frogging at 8,000 feet over El Paso with a seemingly solid mass of sand billowing below us like a turbulent yellow sea. That night we reached New Orleans. . . .” — Amelia Earhart
21 May 1937: Day 2 of Amelia Earhart’s second attempt to fly around the world aboard her Lockheed Electra 10E, NR16020. She and her navigator, Fred Noonan, fly from Union Air Terminal, Burbank, California, to Tucson, Arizona, where they stopped to refuel. Earhart’s husband, George Palmer Putnam, and aircraft mechanic Ruckins D. “Bo” McKneely were also aboard. ¹
When Earhart attempted to restart the left engine at Tucson, it caught fire. An unplanned overnight stay was required while the damage was repaired.
“Accompanying me on this hop across the continent was Fred Noonan. “Bo” McKneely my mechanic, and Mr. Putnam. A leisurely afternoon’s flight ended at Tucson, Arizona. The weather was sailing hot as Arizona can be in summertime. After landing and checking in, when I started my motors again to taxi to the filling pit the left one back-fired and burst into flames. For a few seconds it was nip-and-tuck whether the fire would get away from us. There weren’t adequate extinguishers ready on the ground but fortunately the Lux apparatus built in the engine killed the fire. The damage was trivial, mostly some pungently cooked rubber fittings a deal of dirty grime. The engine required a good cleaning and the ship a face-washing.” —Amelia Earhart
¹ Although the standard Lockheed Electra 10E was certified to carry up to 10 passengers, the Restricted certification of NR16020 limited it to, “Only bona fide members of the crew to be carried.” The presence of Putnam and McKneely violated this restriction.
