I call BS.
The SR71 was made of titanium and required the panels to not be tight together to allow for thermal expansion, and it had a special fuel and tanker just for the SR71. The SR71 had a top speed of Mach 3.2 but some say it hit Mach 3.5. Many parts of the SR-71 reached from 400-500 degrees Fahrenheit, but the airframe above the engines reached over 1,000 degrees. Overall, the average skin temperature of the SR-71 was over 600 degrees. The quartz glass in the cockpit was 1.25-inches thick, and was hot to the touch from the inside! Pilots, even with gloves on, couldn’t keep their hands by the glass for more than a few seconds without doing damage
Maybe if it can get to 100,000 feet where the air is thinner, but that is pretty high for air breathing aircraft.
