## Transcript

[0:00](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements) Bomb released.

[0:07](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=7) The crew puts on protective goggles.

[0:14](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=14) The parachute system deployed exactly as calculated.

[0:24](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=24) The bomb is approaching the detonation point.

[0:27](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=27) Altitude: four thousand meters. Three seconds left, two, one, zero.

[0:38](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=38) The explosion was accompanied by an extraordinarily powerful flash of light.

[0:42](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=42) At that moment, the carrier aircraft was forty-five kilometers from the release point.

[0:47](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=47) The flash and the glow that followed, despite the solid cloud cover, were visible up to a thousand kilometers away.

[1:06](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=66) The column of dust rising from the ground quickly grew in volume.

[1:12](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=72) A few seconds after the explosion, the dust column's diameter was about ten kilometers.

[1:26](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=86) At the same time, from the aircraft, which was two hundred and fifty kilometers from the detonation point, a fiery dome of incandescent explosion products was visible.

[1:38](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=98) As it grew larger, the cloud slowly rose.

[1:43](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=103) At its final stage, it reached an altitude of sixty to sixty-five kilometers.

[1:51](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=111) Its diameter was ninety kilometers.

[1:57](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=117) Later, the cloud began to lose its mushroom shape.

[2:15](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=135) Let's recall what the test site looked like before the explosion.

[2:25](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=145) Now it looks very different.

[2:31](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=151) For dozens of kilometers around, the ground was scorched by the blast.

[2:46](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=166) Entrances to the underground instrument buildings were destroyed.

[3:06](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=186) All the recording and measuring equipment at the test site worked properly.

[3:13](https://www.translate.mom/transcript/xLlGl4bm0R3Y/en/nuclear-bomb-test-explosion-mushroom-cloud-and-measurements?t=193) The data obtained made it possible to determine the actual yield of the explosion, the nature of the nuclear reaction, the accuracy of the device's automatic triggering and a number of other factors.
