I wonder what America's next generation bomber will be. We had the legendary B-52, B-1 Lancer, F-117 Nighthawk, and B-2 Spirit. What's next? Northrop Grumman teased their new plane in this superbowl commercial, and it looks like it won't be a UAV, with the man in the flight suit approaching it.

Silbervogel, German for silver bird, was a design for a rocket-powered sub-orbital bomber aircraft produced by Eugen Sänger and Irene Bredt in the late 1930s. It is also known as the RaBo (Raketenbomber or "rocket bomber"). It was one of a number of designs considered for the Amerika Bomber mission. When Walter Dornberger attempted to create interest in military spaceplanes in the United States after World War II, he chose the more diplomatic term antipodal bomber. Concept

The design was a significant one, as it incorporated new rocket technology, and the principle of the lifting body, forshadowing future development of winged spacecraft such as the X-20 Dyna-Soar of the 1960s and the Space Shuttle of the 1970s. In the end, it was considered too complex and expensive to produce. The design never went beyond mock up test.

The Silbervogel was intended to fly long distances in a series of short hops. The aircraft was to have begun its mission propelled along a 3 km (2 mi) long rail track by a large rocket-powered sled to about 1,930 km/h (1,200 mph). Once airborne, it was to fire its own rocket engine and continue to climb to an altitude of 145 km (90 mi), at which point it would be traveling at some 22,100 km/h (13,700 mph). It would then gradually descend into the stratosphere, where the increasing air density would generate lift against the flat underside of the aircraft, eventually causing it to "bounce" and gain altitude again, where this pattern would be repeated. Because of drag, each bounce would be shallower than the preceding one, but it was still calculated that the Silbervogel would be able to cross the Atlantic, deliver a 4,000 kg (8,800 lb) bomb to the continental US, and then continue its flight to a landing site somewhere in the Japanese held Pacific, a total journey of 19,000 to 24,000 km (12,000 to 15,000 mi).

Postwar analysis of the Silbervogel design involving a mathematical control analysis unearthed a computational error and it turned out that the heat flow during the initial re-entry would have been far higher than originally calculated by Sänger and Bredt; if the Silbervogel had been constructed according to their flawed calculations the craft would have been destroyed during re-entry. The problem could have been solved by augmenting the heat shield, but this would have reduced the craft's already small payload capacity.[
 
With the P-51 Mustang's six M2 Browning machine guns, did they fire in a sequence, or all at the same time?
 
I live about two hours from Pensacola, Florida, and the Naval Air Stations there is the home base for the Blue Angels. The team flies practice demonstrations every Tuesday and Wednesday, and the practices are open to the public, and well-attended. They have bleachers for around a thousand people and plenty of space for chairs.

I've never been to a practice show, though, until this past Tuesday, when a photography groups I'm in made the jaunt.

The viewing area for the practice show is at the far right end of the runway and not at the actual show center, so the point of view is different. You don't see the ground activity for the boarding and startup, but you don't miss anything else; you just see it from way down at the end.

The famous photo pass is the tightest formation flown by any team in the world, with at little as 18 inches separation from the wingman's canopy to the leader's wingtip. The pass is simply a long circle begun behind the crowd, crossing into the showline at the right and passing in front of the crowd. As far right as the viewing area is for practice, they came practically right overhead, and I got this sequence.

(Full overcast, so not the best light for photography, although the overcast was high enough not to interfere with the show.)

1.
From behind and to the right. If straight ahead from your seat is 12:00 o'clock, this is about 4:30. It shows both how tightly they form up, and that they form up with each aircraft offset to the right (not symmetrical) to give a better perspective for the ground viewer.

2.
Passing ahead. Without that offset in the formation, #3 would seem to have a lot of space to the leader, #2 would be almost hidden, and #4 would be hidden the same way under #3.

3. OK, wingtips, there.....

4. OVERLAPPING???!?!??! Srsly?!??

5. From behind, we see that we were tricked by the perspective. He actually had at least a foot, foot and a half of clearance! :boggled:

Great shots! I've seen them at those practice sessions more than I have at actual air shows I think. My family used to go to Pensacola almost yearly since my dad went through flight school in the Navy there. Such a cool place...

Awesome photo and cool story I came across on Reddit.

2P4JgXl.jpg


L->R: C-141 Starlifter, XB-70 Valkyrie (1 of 2), and YF-12A Interceptor.


So other than there being a Valkyrie in that picture, the story behind that YF-12A being there is neat in a 60's US Air Force kind of way.

The setup for the story is that President Johnson formally announced the A-11 to world for the first time. This would eventually become the SR-71. It gets good...

The President’s reference to the “A-11” was of course deliberate. “A-11” had been the original design designation for the all-metal aircraft first proposed by Lockheed; subsequently it became the design designation for the Air Force YF-12A interceptor which differed from its parent mainly in that it carried a second man for launching air-to-air missiles. To preserve the distinction between the A-11 and the A-12 Security had briefed practically all participating personnel in government and industry on the impending announcement. OXCART secrecy continued in effect....

The President also said that “the A-11 aircraft now at Edwards Air Force Base are undergoing extensive tests to determine their capabilities as long- range interceptors.” It was true that the Air Force in October 1960, had contracted for three interceptor versions of the A-12, and they were by this time available. But at the moment when the President spoke, there were no A-11’s at Edwards and there never had been.

Project officials had known that the public announcement was about to be made, but they had not been told exactly when. Caught by surprise, they hastily flew two Air Force YF-12A’s to Edwards to support the President’s statement. So rushed was this operation, so speedily were the aircraft put into hangars upon arrival, that heat from them activated the hangar sprinkler system, dousing the reception team which awaited them.

I feel like this picture and this story sums up the Air Force in the 60's pretty well. :lol:
