Jeff Bird It's the smoking gun view. It was not available for a few days because they had to develop the film. If you watch the CNN live coverage, you CAN see the plume right at the end (before it switches to the side view closeup). The camera focuses twice, on the 2nd one you see a yellow flame that appears to be coming for the SSME area, of course it's an optical illusion and it's actually the plume from the joint after the H2 tank was leaking and feeding the plume making it larger.

More importantly, it shows the SRB rotate away from the bottom of the ET and into the top 0:24

36 years later, I had never seen this entire angle previously. Still as painful as the day it happened.

Weren’t these cameras automated and tightly protected, filming via a series of mirrors? You couldn’t have human camera operators that close to the launch site, they (and the camera they held) would’ve been wiped off the face of the Earth.

@@hal560 The pad cameras are the ones you're thinking about. Those were (and still are) automated. These long-range tracking cameras are within the non-public areas, but still far enough from the launch pad to allow for human operators. In 1986, these would have been operated by human camera crew members. Search KZread and you'll find an amateur video shot from within the NASA grounds, a mile or so from the launch pad, where after the explosion happens the folks outside are told to take shelter in case of falling debris ...

From this camera angle you can see for how long hot propellant exhaust was exiting via the seam in the starboard SRB. That hot gas was firing against the side of the external fuel tank for some time before that part of the tank finally got too hot and it exploded.

0:01 The flames appears on the right booster. The O-Ring fails due to the cold weather and wind shear.

The documentary was right. It resealed and then the strong winds open it back up again.

To add to this, the added aerodynamic force of throttling up was likely what caused the SRB to disassemble at the moment it did. Prior to that, it was gradually losing integrity.

Why in all the videos we watch of this tragedy always show the rocket boosters instead of trying to see where is the capsule and where it going to land.

Even now I don't feel comfortable with anything running at 104%.

You can tell right when the tank starts leaking hydrogen. The color of the exhaust changes.

Larry Malloy was responsible.

Significantly, but not solely. He caved to pressure coming from the Executive branch (probably a cabinet-level post, though we'll never know for sure).

Supposedly, this camera angle was not part of the live TV cameras available to Mission Control during the launch. If it was, flight controllers would have seen the O-Rings being burned through and would have ordered Challenger's astronauts to separate the orbiter from the external tank/solid rocket boosters and make an emergency landing or ditching in the ocean....something the astronauts probably would have survived.

This angle shows the fire.....sad

One reason they only found fragments of the right wing while the left wing came out of the cloud completely intact : The RH SRB broke free at the lower attach point, swung out and hit the right wing. Can really see how the plume seems to "rotate" away from the tank right before the breakup.

こちら側からの映像は、大手メディアには意図的に伏せられていたんでしょうね。

It's interesting for me. Could the astronauts be saved if the burn through of the booster would have been noticed before the explosion? Could the Mission Control center detach the boosters or the spaceship from fuel tank at that moment and then land it successfully?

Even the deceleration of losing the boosters (if it were possible) might have ripped the remainder of the stack apart. Remember what you're seeing isn't technically an explosion, but the breakup of the orbiter due to aerodynamic shear after the tank comes apart. Even if the orbiter and tank survived an SRB separation, they weren't high enough to turn around and return to the launch site or get across the Atlantic for an emergency landing.

Good question! A physicist can give a (much) better answer, but essentially the forces on the orbiter were incredible and destructive compared to the forces on the SRBs. Technically, this wasn’t an explosion, more an uncontrolled disassembly.

The big flaw with the shuttle was always the abort ability, being on the side of the rocket rather than on top of it like apollo made it difficult. Also the data and telemetry mission control had at the time didn't show what was about to happen for them to react, it should never have launched against engineers recommendations.

@@iranmaster You could not separate anything while the solid rocket motors were lit. The 2 minutes from launch until they separate the solid rocket boosters, nor can you turn off the solid rocket boosters. There is no abort mode. The solid rocket motors cannot be unattached from the External Tank while running, because their thrust keeps the connections locked into place. You could unattach the orbiter (the shuttle plane) from the Tank and rocket motors but very bad things would happen at these speeds. Most definitely would cause the exact same explosion and breakup of the vehicle if you tried. The shuttle was a dangerous, expensive machine and thats why it was retired. It was unsafe and overly complicated.

NASA has but has to work hard and very serious about a better way to save astronauts so this will never happen again!😞
