North American XB-70 Valkyrie
Yay! the coolest bomber has been made! not many recent XB-70s on SP. I always loved the XB-70, I have been trying to got to the air force museum in Ohio to go see this feat of aerospace engineering!
Whats NASA.gov to say?
The B-70 Valkyrie, with a planned cruise speed of Mach 3 and operating altitude of 70,000 feet, was to be the ultimate high-altitude, high-speed manned strategic bomber. Events, however, would cause it to play a far different role in the history of aviation.
To achieve Mach 3 performance, the B-70 was designed to "ride" its own shock wave, much as a surfer rides an ocean wave. The resulting shape used a delta wing on a slab-sided fuselage that contained the six jet engines that powered the aircraft. The outer wing panels were hinged. During take off, landing, and subsonic flight, they remained in the horizontal position. This feature increased the amount of lift produced, improving the lift-to-drag ratio. Once the aircraft was supersonic, the wing panels would be hinged downward. Changing the position of the wing panels reduced the drag caused by the wingtips interacted with the inlet shock wave. The repositioned wingtips also reduced the area behind the airplane's center of gravity, which reduced trim drag. The downturned outer panels also provided more vertical surface to improve directional stability at high Mach numbers. Attached to the delta was a long, thin forward fuselage. Behind the cockpit were two large canards, which acted as control surfaces.
so most builds I talk about making the plane and what cool stuff it has, well that's not true anymore! ima tell you about the real aircraft now! If you are as into this airplane as I am you may want to look at this NASA sheet on the airplane and what it does to get to Mach 3. there is also this Video by a guy on YouTube you may find interesting! also, there are a lot of old videos of the plane when it was in a photo shoot for the USAF to show off its amazing plane. when a F-104 chase plane got stuck in the massive planes wake turbulence and its left wing dipped. the pilot pulled up but had been swung up and over while upside down. the F-104 teared both of the XB-70s vertical stabilizers off. this resulted in the loss of the XB-70, the loss of its pilots, and the death of the F-104.thankfully this hasn't happened with any USAF plane in a great amount of time. here is a picture of the accident. please be respectful.
you can see both T-38 and a F-4 Chase plane
here's an animated picture showing what it looked like. this was a major set back and the second XB-70 had technical issues. before you knew it a smaller, faster, and more cost effective high speed plane came along. The SR-71 Blackbird.
Sorry to start on a sad note, but I think this had to be said.

Hope you like my build! and....
