This might be another case of the NASA/STS definition differing from the typical definition, but typically this is not the "critical angle of attack." Crit AOA normally is maximum coefficient of lift (irrespective of drag) aka stall. The speed referred to in this video is maximum lift/drag ratio, which is a smaller AOA.
Yes, you're right I confused max L/D and max L. That was a silly mistake on my behalf and I should have been more careful with my terminology. However, the front and back side still remains in the context of the L/D curve, just imagine "Critical AoA" replaced with "Max L/D AoA". Thanks for pointing it out, if you don't mind I'll pin your comment so others can get the correction.

Awesome video! The Space Shuttle is a remarkable vehicle, as it had to deal with all of the challenges of spaceflight and aeronautics, and you covered that very well in this overview! I can't wait for your next video
The way the universe has been made is that if an object over a certain size is trying to get into our atmosphere that because there is no air it is being forced out of the Earth until it has reached a point on the Earth where there is hydrogen and oxygen which is creating gravity and if it does not a bounce's backout and this is what is preventing asteroids from going into our atmosphere is this field where there is no oxygen and in order for us to effortlessly overcome this we need to make a space elevator and this way the elevator will not be of such a large size that The weightlessness is forcing the elevator back Of the atmosphere and the way to make an elevator is by making a 100 km ball and putting an elevator inside of the ball and this will make it so we can go to the outer atmosphere and launch from there and we can effortlessly travel anywhere in space The reason why the space shuttle is having such a hard time entering is that it is too big and because of its size it has to move thousands of miles per second because the Earth sees it as an asteroid and it is trying to destroy it from hitting the planet Earth Whereas an elevator would not interfere with t The Area where there is no oxygen because the elevator is so small and the 100 km ball would also provide a gravitational force around itself which would protect the elevator from the weightlessness factor that the space shuttle suffers when it tries to re-enter
One thing I find amusing is that despite the shuttle's reputation as a flying brick, if you took a shuttle and another delta winged craft, say Concorde for example, and dropped them both from 50,000 feet Concorde would hit the ground long before the shuttle would as the shuttle of the two is actually the better glider!
Wow congrats on 15k subs, I remember when you were only at 2.3k! I got very excited this morning when I saw that you posted a new video! Hope you are staying safe and can’t wait for more of your amazing content!
Even if the shuttle didn't serve its purpose of bring cost down, but I am still proud to hang pictures of it on my wall! Good job, you earned a new subscriber!
Everybody who's played Kerbal Space Program knows, how difficult it is, to design a re-entry plane that has a controllable AoA and doesn't flip into the airstream either nose-first, tail-first or worse yet, alternating between the two.
It was an interesting complexity of engineering no doubt, but just a massive waste of money time and worst of all lives. Our mighty iconic Saturn V never should of just been canned and forgotten about for the Space Shuttle. I mean, omG, I always shudder to think what she'd be about today had we kept her alive all these years with refurbishing retrofitting upgrading and whatnots!! (?) She was impressive on 1960s technology alone and actually capable of next step being Mars. Such a literal waste of proven awesome rocketry.
Another awesome video, Ben! The animations, diagrams, and graphs are all easy to interpret and understand and the voice over is easy to follow. The particle effects look amazing with the glow and the bright colors really pop. I learned a lot in this one, especially about the re-entry phase maneuvers. I look forward to the next one. Oh, and thanks for the shoutout!

During re-entry of a spacecraft not just the space shuttle the astronauts/cosmonauts would lose contact with mission control because the heat generated during re-entry prevent radio signals from coming through.
If we’re rotating counter clockwise looking from the North Pole down, then it’s fair to say the majority of the ones we’d have time to see in the ***Night*** sky would be travelling west to east. Going east to west would be against the atmosphere and burn up too quickly…
If it wasn’t crazy enough that a ‘flying brick’ aka Shuttle was actually a glider for landing I was stunned to learn that the ‘flight corridor’ had to factor in a short phase during which it was planned to skip off the atmosphere due to an initial high angle of attack to bleed off a large amount of re-entry speed. Then land on the relative postage stamp of a runway.
Hello, I am a player of Manual Docking. It is very hard to do mission 5, aka Skylab Visit because of low propellant. Can you add more propellant on mission 5?
A better question is at what point does the space shuttle synchronize with the air that is synchronized with the planet so that the planet does not continue to spin while they're landing. Imagine spinning a basketball on your finger and a bumblebee insists on trying to land on the ball. No matter what the bumblebee does when it hits the ball it is spinning. So Nasal lands their spacecraft the Earth it is no longer spinning or we would see some nasty disasters and we would never see a plane land on the north south runway. How does a plane take off from a spinning surface and stay synchronized with it? Imagine you are in a helicopter taking off from a spinning basketball once you leave the ground is the basketball going to continue to spin or are you going to synchronize with the air around the basketball and now it appears like the basketball is not spinning. Air moving around a helicopter would allow it to hover and wait for its destination so either the Earth isn't spinning or air takes on a unique quality that we could call magic. You don't live on a spinning ball
1:35 , This incorrect overshoot drag just means you will over shoot the target point, there is no skipping out of the atmosphere or altitude rise. The aircraft is still dropping, due to speed decrease.
Criticism: please provide some acknowledgement of your data sources, e.g. Harpold's report. Praise: Great job putting together a difficult topic into a cohesive, understandable lesson!
Thanks, I spent a long time and many script drafts to get all the points presented in a precise way I was happy with. I have to politely disagree on the criticism, but I'll give you my reason. I am not producing videos in any academic capacity and I don't wish to treat my videos as if I am. I feel that the way in which I researched and wrote the video provides enough separation between my work and any particular source to the point of requiring an "acknowledgement". As a matter of fact I had not previously come across Harpold's report until reading your comment, I wish I had. However I think that further illustrates my point.
Hey just a quick question in the beggining of the video we hear "Endeavour Houston we see a nominal MECO Welcome to space" just wondering in which mission did that transmission occur?
Re-entry is a complex subject, and radically different schemes have been used. The X-15, the Mercury and Gemini capsules, the Apollo capsules, the Shuttle, the SpaceX Starship, and Artemis/Orion, all used very different ways of handling the stresses of re-entry. (Artemis/Orion has an interesting way of handling return from the Moon, and will probably surprise a lot of observers.)
I'm honestly surprised about this. I thought I knew everything about the space shuttle and its re-entry after nearly four months, and I just learned a ton of new things. New subscriber earned.
What you animated as as 'bank angle' is actually yaw, usually controlled by the rudder of an aircraft.The wings are drawn as being kept level - it incorrect. Bank is the displacement angle to the horizontal after an aircraft has rolled along the direction of flight (using the ailerons) which is exactly what the Shuttle performed during its S-turn maneuver - it used its ailerons
I've been wondering: If the Columbia crew had known there was a problem with the left wing, could they have altered the entry profile to minimize the problem, and possibly make it through? My understanding is that at the time of the breakup, they were past the point of maximum heating-or, at least, what normally would have been past the point of maximum heating.
A friend of mine in my Freshman year at Harvey Mudd College did a simulation for these parameters for Shuttle Re-entry as his previous years' senior project. Was it the one used? I doubt it but using any amount of computing power for that by a buncha undergrads in '78 was purty cool.
This video was AMAZING. I had no idea that non-zero bank angle was used at all during re-entry, and certainly not that it was critical for a successful re-entry! What sort of maximum bank angles did orbiters typically reach in the re-entry guidance phase?
Very informative SS.....just out of interest, timewise roughly how long is it from red hot re-entry to the very cold temps of the stratosphere ? In other words that transition period ?
Many many thanks for this awesome video, with very cool animation and amazing explanation...Love your work man. I request you to please make a video on Orbital Mechanics covering all aspects like this one.

How do i unlock every level in manual docking please help
To unlock a mission, you need to complete the previous one.
During re-entry of a spacecraft not just the space shuttle the astronauts/cosmonauts would lose contact with mission control because the heat generated during re-entry prevent radio signals from coming through.
If we’re rotating counter clockwise looking from the North Pole down, then it’s fair to say the majority of the ones we’d have time to see in the ***Night*** sky would be travelling west to east.
Going east to west would be against the atmosphere and burn up too quickly…

I’ve always wondered why the shuttle didn’t just naturally point nose down (facing the wind flow) as any winged airplane would. There’s the answer.
I don't understand how increasing bank increases drag.. if you are decelerating on the back of the lift curve, increasing bank would reduce drag
Hey!! Iam enjoying the game manual docking, one advice could you add a lunar landing and roving mission. It would just be amazing.
Excellent animation and explanation. You got yourself another subscriber. Do you have anything similar on capsule reentries?
what a fantastic explanation of bank angle, and its utility. amazing video. thank you so much, DA
This was so intense, I watched it twice!
Very well put together video. Blew my mind when I realized you only had 15k subs. Keep it up and I see many more in the future. Excellent work!
Those pilots are bad asses, sons of a guns.
This video is simply amazing
I already watch 3 times. And the YT keep sending to me watch again.
useful video i re enter and landed safely my shuttle on Kerbal Space Program
