1. VISION: NASA TV slate of approximate time period of communication, with overlaid audio:
SOUNDBITE (ENGLISH) Communication between various NASA Mission Control employees:
Just taking a few hits here. We're right up on top of the tail, not too bad.
No commonality between all these tyre pressure instrumentation and hydraulic returns instrumentations?
No, sir. We've also lost the nose gear, down talk back on the right gear, down talk back.
Nose gear and right main gear, down talk back?
Yes, sir.
And flight econ'?
Econ'.
I got four temperature sensors on bottom line data that are all scale low.
Columbia out of communication at present with mission control, as it continues its course towards Florida.
I didn't expect this type of a hit on comm'.
GC, how far away from UHF? That two min o'clock good?
Affirmative, flight.
Columbia-Houston comm' check. Columbia-Houston UHF comm' check.
(inaudible) in smaller persistent case than that. In other words, we shouldn't expect as big as a change uncomfortable with 1500 feet down
Flight controllers are standing by for Columbia to move within communication range at the Merrit Island tracking station in Florida, to regain communications with Columbia
Okay
Columbia Houston UHF comm' check.
In flight, GC
Go
(inaudible) is taking one of their antennas off into a search mode

Final flight
Go ahead flight
Did we get, have we gotten any tracking data?
We got a blip of tracking data. It was a bad data point, flight. We do not believe that was the orbiter. We are in a search pattern with our c-bans (phonetic) at this time. We do not have any valid data at this time.
Okay. Any other trackers that we can go to?
Let me start talking flight, navigator
Communications with Columbia were lost at about 8am central time (0400gmt), about 10 minutes ago
Flight GC, Lock the doors.

STORYLINE
Conversations between the flight controllers, released on Tuesday, suggest engineers were waiting helplessly at mission control while the space shuttle Columbia came apart on the threshold of space.
Flight director Leroy Cain quickly shifted his attention from landing the craft at the Kennedy Space Centre in Florida to saving computer data that might help experts learn what destroyed shuttle.
Thirty minutes before the landing, Cain was concerned about which end of the Kennedy runway Columbia commander Rick Husband would use to guide the shuttle to landing, a relatively minor issue.
In fact, there was no hint of any problem until the final six or seven minutes of the flight when Jeff Kling, the maintenance, mechanical arm and crew systems officer, reported a sudden and unexplained loss of data from spacecraft sensors.
Cain quickly asked if there was anything common to the sensors and got bad news in reply.
Kling said there was no commonality, suggesting there was a general failure instead of a single system.
In short order, flight controllers begin reporting a litany of bad news.
There is evidence of small collisions on the tail and signals are cut off from the nose landing gear and from the right main landing gear.
Then more sensors are lost and the drag increases to the left.
Capsule communicator Charlie Hobaugh begins a series of radio calls to Columbia.
There is no response as the minutes tick down toward a planned landing at the Kennedy Space Centre.
The communication checks continue.
So does the silence.
A radar station near the Kennedy Centre then says it is putting its radar in a "search mode".
This meant nobody could leave Mission Control or even make phone calls.

I remember that horrific day. Those seven brave astronauts never made it home. RIP.
I heard and remember the sounds of the reentry, I live in e tx, we had no idea what it was
That they ended on "Lock the doors"... Anyone who remembered Challenger and heard that had to have known instantly.
What happened to the Columbia is that they were incapacitated (unconscious) within 90 seconds of the Columbia becoming uncontrollable when the crew module rapidly depressurized, and dead within a few minutes from blunt force trauma. (The shuttle began breaking up from extreme aerodynamic forces about 60 seconds after it became uncontrollable, with the crew module breaking up about 30 seconds after that.)
The long answer is significantly more complicated, and thoroughly unpleasant to consider, even knowing that they were already unconscious or dead before the rest of it happened. NASA did a “crew survivability study”, which has since been made public. (Redacted to remove any private details out of respect for the crew and their families.) It describes exactly what happened to the crew in such a way that, even though specific details were either removed or not put in, it is far clearer than most people care to imagine (and you can't help but imagine it while reading the report).
what essentially happened is that when the crew module (CM) separated from the forebody after the catastrophic event (CE) of the shuttle breaking up around 200,000 feet at Mach 18, it rapidly depressurized. (The crew members who had their helmets on - 6 of 7 - didn't even have time to pull their visors down.) They lost consciousness within 10-15 seconds. While circulation may have continued for a short time, they could not have regained consciousness even if the CM had dropped mostly intact to a breathable altitude. Things that happened after that were also lethal, but they were essentially already dead before the CM broke up.
At that point, the CM spun around on all three axes with such force that the crew's shoulder straps broke, leaving them restrained only at the waist. Their bodies were spun around while their heads banged around inside their non-conforming helmets, inflicting lethal head wounds and damage to spines, etc. Had they been conscious, they could have braced themselves sufficiently to prevent such injuries, but they were not.
Within 30 seconds, the CM broke apart from the aerodynamic forces, exposing the crew to extreme winds and high altitude. The wind caused lethal blunt force trauma, as did being struck by pieces of the CM as it broke up around them.
The crew's remains, or rather what was left of their remains, eventually fell and struck the ground - identified as the last lethal event in the report
Thanks for that now i understand it but i have a question if you dont mind when the challenger exploded and the crew blew away from the shuttle in the cockpit do you think they died before they hit the ocean? or do you think the ocean impact killed them?
@@jasonlinton9902 they definitely were unconscious if not dead from the G’s.
But I don’t think any of us could make a conclusion other than from analysis
@@jasonlinton9902 they for sure died briefly before, explosion shockwave, injuries, depressurization, extreme wind pressure and temperatures all combined killed them quicker. At the absolute worst, they would be unconscious before impacting, if that serves as a relief. We know only 3 of them were defo conscious after the very explosion (only 3 controls manually operated)
@@jasonlinton9902 Challenger crew was alive and at least three were most likely aware of everything, before ocean impact. Several astronauts have said that and the evidence seems to support. It had to be awful. At least in the case of Columbia, they were all out and unaware of what happened.
I remember this day. I was playing Everquest, trading in the bazaar, when someone said: "We lost a shuttle." That moment, including the green text, is still engraved in my mind. May they rest in peace.
I was trying to watch rugrats on the nick on cbs saturday morning block and was mad that this interrupted that.
"Lock the doors" ...damn
Quite the slap in the face losing crew during reentry.
as opposed to? launch? reentry is definitely an extremely dangerous period for a nasa space shuttle
Climbing the mountain is the east part. Getting down is the hard part.
@@emilyt6925 Getting down _alive_ is the hard part
Why is it a slap in the face? Accidents happen. How many plane crashes have there been while the plane is on approach? Pretty much most plane crashes happen either on takeoff or landing. Few have happened in flight. That said, judging by the name you're using it doesn't surprise me you would make such a stupid statement.
Yeah “sure”.
Like you’re the expert on space flight😂😂😂
Where are the recordings and transcripts of all the shuttle radio conversations that took place between the time they entered California and the last transmission of "Roger, uh"
you got the wrong shuttle. It s from the challenger's accident audio i think
@@unhommequicourt Official last transmission is COLUMBIA (Commander Rick Husband): ``Roger, buh.
@@mitzimitzi2608 pretty sure it was "uh oh" if you listen to the audio
Clearly states Columbia repeatedly in the recording
@@dukeford8893 whoops
If anything good can be derived from this disaster? It's that despite the horrible nature of this disaster and it's subsequent loss of life, we gain more understanding of the difficulty of space travel and make the endeavor that much more safer. Perhaps one day we will look back on the brave crew who felt the need for human understanding outweighed the inherent risks and difficulties, to the day we truly learn how to fly to the stars. They paved the way for the future of humanity.
The transcript starts after the last transmission from Columbia.
Did they mean lock the doors at the station or the doors on Columbia?
Lock the doors at Houston.
"Columbia, Houston! Comm check!" 😕
That's exactly what I did when someone was ghosting me on Tinder... (before blocking/unmatching them of course)
If you want horrific, listen to the audio from Apollo 1.
Fire in the cockpit. 💔
This is AP? Damn, they must not have given shit when they put this up.
can't u write the spelling of Columbia write
George MMA Ok, not everyone speaks english correctly. In fact, many other languages have many more speakers than english. So, stop being racist and start respecting other languages for once.
Ashok was clearly joking on the second "write". It's a good point because this is AP's channel! One would expect some understanding of the differences between Colombia and Columbia.
MysticKoolaid808 it’s a joke u twit
cant you go eff yourself?
Ashok Verma you are very dumb and smelly
I don't know what to say badly garbled message
My last words on WhatsApp to the date who ghosted me were "Columbia, Houston. UHF comm check."
No wonder why u were ghosted then. This isn't funny.
Colombia is a country.
So is Ireland.
So is england
@@rddzXS So 'isn't' Columbia.
So isn't Russia
Mt bom...🐳❄🌚🐞🦋
