1967 - NASA/Air Force XB-70A Valkyrie #1 landing - not Miami-related

This is obviously not Miami-related but in the 1960's this was my favorite aircraft and it still amazes me that our country could build something so extraordinary almost 50 years ago and we haven't seen anything that comes close to the XB-70 since then.

Title: XB-70A landing with drag chutes deployed

Description: This photo shows the XB-70A #1 rolling out after landing, employing drag chutes to slow down. In the photo, the outer wing panels are slightly raised. When the XB-70 was flying at high speed, the panels were lowered to improve stability. The XB-70 was the world's largest experimental aircraft. It was capable of flight at speeds of three times the speed of sound (roughly 2,000 miles per hour) at altitudes of 70,000 feet. It was used to collect in-flight information for use in the design of future supersonic aircraft, military and civilian. The major objectives of the XB-70 flight research program were to study the airplane's stability and handling characteristics, to evaluate its response to atmospheric turbulence, and to determine the aerodynamic and propulsion performance. In addition there were secondary objectives to measure the noise and friction associated with airflow over the airplane and to determine the levels and extent of the engine noise during takeoff, landing, and ground operations. The XB-70 was about 186 feet long, 33 feet high, with a wingspan of 105 feet. Originally conceived as an advanced bomber for the United States Air Force, the XB-70 was limited to production of two aircraft when it was decided to limit the aircraft's mission to flight research. The first flight of the XB-70 was made on Sept. 21, 1964. The number two XB-70 was destroyed in a mid-air collision on June 8, 1966. Program management of the NASA-USAF research effort was assigned to NASA in March 1967. The final flight was flown on Feb. 4, 1969. Designed by North American Aviation (later North American Rockwell and still later, a division of Boeing) the XB-70 had a long fuselage with a canard or horizontal stabilizer mounted just behind the crew compartment. It had a sharply swept 65.6-percent delta wing. The outer portion of the wing could be folded down in flight to provide greater lateral-directional stability. The airplane had two windshields. A moveable outer windshield was raised for high-speed flight to reduce drag and lowered for greater visibility during takeoff and landing. The forward fuselage was constructed of riveted titanium frames and skin. The remainder of the airplane was constructed almost entirely of stainless steel. The skin was a brazed stainless-steel honeycomb material. Six General Electric YJ93-3 turbojet engines, each in the 30,000-pound-thrust class, powered the XB-70. Internal geometry of the inlets was controllable to maintain the most efficient airflow to the engines.

The fantastic looking XB-70 was a very expensive white elephant. Basically incapable of low altitude penetration when the Surface to Air Missile made high altitude penetration impossible. Compared to the ICBM the B-70 was not cost effective nor anywhere as likely to complete it's mission.

Way ahead of its time.
This could have replaced the B-52 as a heavy bomber. Amazing how the commercial SST resembled it.
I built the plastic model kit of this "futuristic" jet made by Aurora in the mid 1960s.
At the time I thought it was a made-up design to sell model kits. Little did I know.
