Thank you for posting this video 🎉. You have a new subscriber. Keep up the great 🎉. My favorite ❤️ has always been. The SR-71 Black Bird, A10 Warhog, & The Apache Helicopters..
Getting a pilot's license is pretty easy, and it's not crazy expensive. Of course you won't be flying one of these but if you are low, it's seems a lot faster.
9:46 There are at least 2 A-12's remaining. There is one on display at the US Space and Rocket Center, Huntsville, AL. It is commonly misidentified as an SR-71, but it is an A-12.
When you say they? You're obviously not referring to the Canadian government or military, are you? Cause as far as I know the only other thing we might have done ( i.e., is when Canada contributed up to 22. billion to develop space launching capabilities in canada) Via the Harp program, which for all intense purposes probably contributed to the now functional magnetic rail gun. First considered as a defense mechanism to thwart an asteroid.
No doubt I'm touching 50 years old I still remember watching the space shuttle blow up in Middle School I want to Kenwood high School that had the teacher Kristy McCall up on the space shuttle that blow up and every classroom didn't have a TV so we we're mixed with different classes and different grades and still remember teachers looking at us all in the classroom I was in and she didn't even know what or how to tell us anything cause she was just like us ---- like did that really just happen very sad for all of them because they delayed the take off for another day and truly the people working for NASA knew that there was a problem with that big ol ring was suspect of failing NASA really dropped the ball on that and they know it
The goal at the time these aircraft were developed, was outrunning air defenses. That is no longer practical, so they are no longer actively developing such fast aircraft. The hypersonic missile is the focus today.. ie a weapons systems capable of delivering itself, at speeds which there is currently no defense for.
United States rules, yes I'm a cocky American 🏈 who's loves football, baseball, basketball, and boxing! Our plans are the best, our military is the best! And we protect the world everybody is good, we are The beacon of light, we are the good, the GOOD Vs. evil and the world's ! God bless America!
Why? You do know there are secret craft owned by NASA and CIA that exceed the SR71? In fact, this list is only complete for known craft. Many UFOs are military craft.

If you do a little research you will find that the Blackbird did not fly for final time in 1999, it was briefly removed from mothballs during Iraq and Afghan wars early on.
11:09 it's hard to Fathom traveling at 4500 mph! That's faster than any projectile I ever fired out of a gun! Strange thing even a 22-250 firing 3800 feet per second. These things disintegrate on an empty Coke can entering one side whole and pieces exiting the other. And that's copper jacketed lead. Imagine what aircraft grade aluminum would do at that speed! It's hard for me to imagine the human body can even undergo those kind of speeds...
The "need for speed" has been realized to not be the most important thing for fighter planes anymore. They just need to be fast enough, somewhere between mach 1.8 and mach 2. That's why so many of these are old. Most combat takes place around mach 1.2 or less.
AAAH😎....!!, YEAH........!!, YO.....................!!, ℹ️THNK💭......!!, THE NASA X-15 WAS OUR FASTEST JET 🛩 FLOWN, BUT WAS NOT PRACTICAL FOR AIR-CRAFT USE IN OUR AIR-FORCE, BUT AWESOME👏 BIRD 🦅 FOR IT’S HAY-DAY IN THE 1960’s HERE PEOPLE😎🇺🇸
plus the fact the u2 and the sr71 were still vunerable no matter what speed or altitude they could fly at and cost to much to operate ... i think the sr71 was tracked by a missile and it gave the usaf a fright when they thought nothing could touch it , as it turned out they were right misiles and radar rule the skies really
In my humble opinion, the current space planes such as dream chaser, x37b, and star raker make these lists moot. However, these are very cool fast movers.
You retro fit your old aircraft for space when it becomes an Issue to fight in space, You still create new Fighter Space crafts but as the Air battles move into space you have to use up what you already have. Because of Resource supply issues.
Defeating heat is the key to prolong flight at high speed. There must be a series of barriers that remove the heat as it soaks into the airframe. Anything faster than the SR-71 does not stay at those high speeds for more than a few minutes at a time.
The space shuttle was not built for speed but it did orbit at 17,500 miles/hour. That smashes anything else. So, there has to be an altitude limit for this contest.
Should have skipped the russian ones, and included the F-22 and F-35, and if you have the X-15 you might as well include the Space Shuttle too, both are liquid fuel rockets with wings. Or a missile with a cockpit if ya prefer lol. ;)
@@allanullman7754 Do you mean the XB-70 Valkyrie? Nah that plane is American in the first place and way faster cooler than a Concord lol. I'm not really biased for America, I'm Canadian, I'm just biased against Russia lol. Screw Russia, well mostly just screw Putin is what I was really trying to say in the end. I don't see much similarity to the Concord, maybe just the canards but that's about it. The wings on the other hand are a dead ringer for the Avro Arrow, 100%!
@@Thephilipcartmelexperience I know the Americans copied off it lol. What was that documentary, there was a very similar plane they used for testing, what was it called? It lead to most of the super sonic aircraft and they stumbled into super cruise I think. Anyway, suprisingly a lot of stuff was invented in Canada. Telephone and radio were invented here, even though americans also try to take credit for radio, it's not true! I could ramble on..
The U.S. ScramJet II is the fastest by far traveling 3,069 mph. It's only flown 4 times so far and unmanned. The scientists took the idea from a Borg concept. The prototype is called 709.
In 1952 the British LIGHTNING flew at MACH 2.27 @ 40,000 ft. Then in 1956, the AVRO CF-105 flew @ MACH 1.98. The BAC TSR-2 flew at MACH 2.15 . Considering how old these aircraft were, why didn't you list them ? Considering they were OLDE FARRTE AIRCRAFT with vintage technology, they would still be viable in a dogfight today.
@@colinbrown4719 I think you're right about those planes being British. However, I have seen multiple videos by British channels that diminish the U.S.'s achievements in aeronautics. So, it goes both ways. Britain did supply some of the early knowledge for G.E. to start building jet engines. Also, they supplied some of the best jet engines to the U.S. Namely those made by Rolls-Royce. But, Kelly Johnson did not go to Britain to get his plane design ideas. He was surrounded by his own U.S. guys, and he was a genius aircraft builder. Look up some history on him. I think you'd find it fascinating.
The problem with supersonic fighters is that they burn up all their fuel just getting there. And the pilots are prone to saving their fuel to run away.
I will never forget, years ago, the day at the Canadian International Air Show that an SR-71 made several passes. As I understand it, she had flown up from Beale, made her passes and then flew back. It actually made me weep to get to see that aircraft for real. As a youngster, reading about the X-15 sent shivers down my spine - and it still does to this day - 58 years later. I have one question for anyone who can help. Why does the Space Shuttle not surpass the X-15 in terms of speed? Thank you for this and best wishes.
Your Mach conversion into km/h is not correct. F15 vs. MiG-31, you don't even have to calculate... Briefly, all you conversions are incorrect. How come?
The Mikoyan-Gurevich MiG-25 could reach Mach 3.2... but only once. After that, his engine was only suitable for scrapping. MiG-25s were limited to Mach 2.83.
My step dad was in the RAF he was lucky to get up close to these craft , literally he had to crawl in tiny spaces of the crafts for maintenance in baking heat almost cooked him alive a few times lol , r.i.p
Honestly from what I could understand is all the retired fastest aircraft.. obviously you will not get the actual data of used fastest jets that are being used now for security reasons. 😊
Have wars ever brought lasting and peaceful solutions for us to live better? No, they only brought misery, pain and poverty so.... NO. The money should be spent to help the country and the people live better. But as long as politicians and crooks exist this will never be possible, only God will soon bring an end to this evil generation. And this day is very near. The Bible foretold what men would be like in the last days. In 2 Timothy 3:1-5 he predicted: But know this, that in the last days critical times hard to deal with will be here. For men will be lovers of themselves, lovers of money, self-assuming, haughty, blasphemers, disobedient to parents, unthankful, disloyal, having no natural affection, not open to any agreement, slanderers, without self-control, fierce, without love of goodness, betrayers, headstrong, puffed up [with pride], lovers of pleasures rather than lovers of God, having a form of godly devotion but proving false to its power; and from this turn away.
Hello, I'm not sure if you are aware, and I'm not being disrespectful, but science deems the edge of the atmosphere, or the edge of space to be 100 km's above sea level, or aprox 62.5 miles up. 102,000 ft is aprox 19.3 miles up. A long way up to be sure, but not the edge of space

There is an obvious, good reason fast aircraft do not have forward swept wings... If anything went wrong, the wing would immediately snap off.
These records are over 50 years old. I suspect todays actual records are top secret.
True. The SR71 actual top speed and ceiling remain classified to this day.
