q-tip Posted April 4, 2015 Report Share Posted April 4, 2015 I didn't know the b52's could do that Quote Link to comment
VFR800 Posted April 4, 2015 Report Share Posted April 4, 2015 Pretty sure it's not at supersonic speed in that pic. Would depend on what height it was at but the B-52 is not rated to be capable of supersonic flight. 1 Quote Link to comment

VFR800 Posted April 4, 2015 Report Share Posted April 4, 2015 It's close though. @ 60,000 ft the speed of sound is 659.8 mp/h or 1062 km/h B-52's top speed is 1037 km/h. Quote Link to comment
Ranman72 Posted April 4, 2015 Report Share Posted April 4, 2015 does the speed of sound change with altitude maybe the guy had a tail wind to hit the speed of sound Quote Link to comment
Z-train Posted April 5, 2015 Report Share Posted April 5, 2015 Hey Z-train, this look familiar? Collings Foundation visited the Denton airport this week. A good turn out despite the weather and happening in the middle of the week. The world's only dual control P-51 Mustang. Made about 6 flights at $2200.00 for an hour. UH-1 Huey that was a Marine Corps gunship in Vietnam. The pilot was really good. When I parked him, he flew a 90 deg. quarter circle around me with the nose of the aircraft pointed straight at me the whole time. He maintained the exact same distance from me during the whole maneuver. One of the ground crew said he likes to show off. I was impressed, and that takes a lot! The B-17 and the B-24. I love the way these big round motors belch smoke on start up. Nose of the B-24 Cell phone cameras give spinning propellers a unique look. [/url] Cpl.Daniel Schaller flew in the 305th BG,365 BS out of Chevleston, England. He had twelve missions over Germany as a radio operator. This was taken on April 22nd 2001 over Tucson when I took him & is daughter on his thirteenth mission. 2 Quote Link to comment

MikeRL411 Posted April 5, 2015 Report Share Posted April 5, 2015 "We have one of those in town." The best of all possible worlds on the B57 is the RB57F. The 60 foot plane with the 120 foot wing span! And the Boeing 747 engines! While at Yokota Air Base Japan I had the pleasure of servicing the prototypes "Patricia Lynn 1 and 2" on their way to "South East Asia" and corrected a major design fault. The body was B57B with updated body electronics. The High Frequency antenna aerial/antenna was pure Copper! On the way from California to Yokota Air Base Japan the pure copper had stretched MAJOR due to air resistance so I had the flight line techs replace the antenna with "Copper Weld" cable [steel core with 4 strands of Copper overlay]! Of course eventually the ephemeral approval cycle with "unknown" sponsors" eventually admitted their error and approved my change, but by that time the initial mission was sucessfully completed!

VFR800 Posted April 5, 2015 Report Share Posted April 5, 2015 does the speed of sound change with altitude maybe the guy had a tail wind to hit the speed of sound http://www.livescience.com/37022-speed-of-sound-mach-1.html The speed of sound varies depending on the temperature of the air through which the sound moves. On Earth, the speed of sound at sea level — assuming an air temperature of 59 degrees Fahrenheit (15 degrees Celsius) — is 761.2 mph (1,225 km/h). Because gas molecules move more slowly at colder temperatures, that slows the speed of sound; sound moves faster through warmer air. Therefore, the speed required to break the sound barrier decreases higher in the atmosphere, where temperatures are colder. Scientists are interested in the speed of sound, according to NASA, because it indicates the speed of transmitting a "small disturbance" (another way of describing a sound wave) through a gas medium. The transmission of the disturbance takes place as molecules in the gas hit each other. The speed of sound also varies depending on the type of gas (air, pure oxygen, carbon dioxide, etc.) through which the sound moves. The first controlled flight to break the speed of sound — also known as Mach 1 — took place Oct. 14, 1947, when test pilot Chuck Yeager breached the barrier using Glamorous Glennis, an X-1 aircraft. NASA's X-43A aircraft flew more than nine times as fast on Nov. 16, 2004, flying Mach 9.6 or almost 7,000 mph. That stands as the fastest speed achieved to date by a jet-powered aircraft. 2 Quote Link to comment
goes2fast Posted April 6, 2015 Report Share Posted April 6, 2015 http://www.livescience.com/37022-speed-of-sound-mach-1.html I never heard about this, any pics of the X-43A? Quote Link to comment

VFR800 Posted April 6, 2015 Report Share Posted April 6, 2015 True and hypersonic flight would be even better. Quote Link to comment
MikeRL411 Posted April 7, 2015 Report Share Posted April 7, 2015 True and hypersonic flight would be even better. Airlines would love it! Warn passengers to go to the toilet before departure and no on board toilets or food and drink service! The entire interior volume consumed by paying passengers, no "waste" creature comforts. 2 Quote Link to comment
