- Failure of the DeltaII rocket on January 17, 1997, carrying the GPS IIR-1satellite for the USAF. The launch is repeated in slow motion and with extra views so that the failure is best seen.
This video combines multiple camera angles of the flight. Includes footage from AFSMMF • Delta II GPS IIR-1 Lau... , • Delta-II rocket Launch... and • Delta-II rocket Launch... .
Research, video cleanup, remastering, and editing by Retro Space HD.
=============================================
GPS IIR-1 or GPS SVN-42 was the first Block IIR GPS satellite to be launched. It was to have been operated as part of the United States Air Force Global Positioning System.
GPS IIR-1 was launched on a Delta II 7925-9.5 launch vehicle, serial number D241, from Launch Complex 17A (LC-17A) at the Cape Canaveral Air Force Station (CCAFS). The launch occurred at 16:28:01 UTC, on 17 January 1997.
Thirteen seconds later, the rocket's flight termination system was activated by its onboard computer. This detonated explosive charges aboard the rocket, causing it to explode. At the time of the explosion, the rocket was 490 m (1,610 ft) above the launch complex.
An investigation determined that the failure was caused by a crack in the casing of the number 2 GEM-40 solid rocket motor, which started to form at T+6 seconds and grew from there.
At T+12 seconds, the Solid rocket booster (SRB) casing ruptured and debris struck the number 8 SRB next to it, causing that motor to fail as well.
One second later, the range safety destruct charges automatically activated, causing the rocket to auto-terminate, which led to the self-destruction of the first stage and the detonation of the remaining SRBs. The upper stages were blasted free.
At T+21 seconds, the Range Safety Officer sent a manual destruct command to terminate the upper stages for safety purposes, resulting in their destruction. The GPS satellite and payload shroud survived intact until impacting the ground. It could not be determined with certainty what had tripped the destruct system on the first stage; possible explanations including a lanyard being pulled, a shock wave from the rupture of the number 2 SRB, or heat generated by the event.
It was the lowest-altitude launch failure at Cape Canaveral since Atlas-Centaur AC-5 in 1965 and only the third total loss of a Delta in the previous two decades.

"We have an anomaly"
No shit, your rocket just blewup.
it'll buff out
*"Oh no."*
- that one announcer during the titan IV explosion, 1998
Wow! Never seen that view of pieces landing! That is insane.
Check out the cars that were destroyed in the parking lot. The launch guys had a hell of a time explaining what happened to their insurance companies.
@@IvorMektin1701 I saw another video where they were interviewing one of the LCC technicians whose truck was destroyed by debris. He described calling his insurance agent to explain that his truck had been hit by a rocket. When the insurance person was like "Say what?" he told the guy to turn on CNN because there was a story running right then. A few seconds of silence later and the insurance guy was like "The check is in the mail."
I love how the announcer goes “we had an anomaly on the launch vehicle but we have lift off…” as a million molten pieces of what was formerly the said launch vehicle is raining down on camera 😂
it will always be funny how they refer to absolute destruction as an "anomaly".. like it's just some minor issue
Yes! If I said that at work when one of the systems goes down, I would get The Eye from my boss!
It it's a minor issue, because it can be replaced easily.
@@Andrecio64 and that would be a valid point if they didn't also use anomaly when there's people on board.. while there are spares.. they're not in situ replaceable
@@philosoaper i have 2 answers for that:
1. Launch Scape System (preserves life)
2. Recruit some more test subjects and reward them with cake if they survive.
I remember when that happened, but I never seen the footage you just showed me. Thank you for the time and effort you put into your video, thumbs up.
“We need to secure the area” girl wtf do u mean there’s literal hellfire retribution and wrath raining from the sky
Looked like deployment of Russian Snow(phosphorus).
I expected some pictures of the damage on the ground. I remember a whole parking lot with cars destroyed...
Yes I remember seeing pictures of cars that had been close to where some of the debris landed. All of the plastic, glass and rubber in them had melted in the heat and had formed a sort of “lava” lying on the ground!
@@garethmurtagh I wonder if the insurance companies covered all this?
@@foxmccloud7055They probably did but were very reluctant. Also keep in mind that there are reinsurance companies who insure the insurance companies.
I was there, not far from the blockhouse. Tense moment for a few seconds. Feel for the guys IN the blockhouse. At least they got new vehicles out of it.
Imagine reporting that to the insurance company. And solid fuel rockets do explode in spectacular fashion, with the solid pieces raining down everywhere ....
I always thought that the SRB that exploded was the one that wasn't lit. but It was a few over to the left. I never knew that.
"We have had an anomaly" I can't this is too funny🤣🤣🤣🤣🤣🤣
Thank you for this video! I was the one who found the AFSMMF VHS archive of the kaboom and digitized it for their UA-cam channel, but I didn't have the resources to do it justice the way you did. As far as I'm concerned, yours is now the authoritative video for this anomaly.
Any guesses what the whining is at T-5 seconds? I've read various guesses. I'd like to find someone who was there to give an authoritative answer.
I'm pretty sure the fts was triggered by the loss of thrust from the 2 and 8 engine going boom. Isn't thst what it's for? The description sounded like they weren't sure why the fts went off.
The Delta is a very reliable rocket, with only very occasional failures like that. OTOH, it's space flight, not civilian air travel, and highly risky.
We have just had an anomaly with the Delta II launch vehicle

We need to secure the area
They used to call them, "anomalies" and now they're what...?
"Rapid unscheduled disassemblies".
спасибо супер
😭😿 poor baby dalta 😿😭🤧🥺
Mayhem is everywhere, are you in good hands?
Well, can't say she isn't positive :).
"...on the pad."?
Yeah, rocket launches just weren't that interesting before SpaceX unless something like this happened.
go boom not good.
I'd say that the Forth of July came early. I wonder how the insurance companies are going to pay for this?
“Anomaly” 😅
"We have had an anomaly" fkcing lol
Algorithm.
"We. Have. Had. An. Anomaly." the absolute COPE. Why dont they just take the L and say "well, it exploded" lmao I never understood the denial in some of these accidents. Just call it an explosion! Saying vague things like that isn't making it come back LOL!
