[0:02](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=2) This dashcam caught Learjet N722 Bravo Delta hitting Military Trail in Palm Beach County on November 1st.

[0:10](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=10) If you blinked, you missed it. The jet appears in just three frames, about a tenth of a second.

[0:17](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=17) A dashcam records thirty frames a second, and its shutter is open for only about two-thousandths of a second each time.

[0:24](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=24) For ninety-four percent of every second, it's blind.

[0:27](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=27) At six hundred and forty miles an hour, the jet traveled thirty-one feet between frames.

[0:33](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=33) So I rebuilt the impact in 3D. The speed, the sixty-five-degree dive, and the timing come from the flight tracking data.

[0:41](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=41) The camera in a car about two hundred and twenty-five feet away was matched to the video. Then I rendered it at one thousand frames per second. That's thirty-three frames for every one the dashcam recorded.

[0:54](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=54) Here's the real video slowed thirty-three times with the simulation laid over it.

[1:00](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=60) The aluminum airframe was instantly pulverized, its thousands of pieces scattered like dust.

[1:08](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=68) The jet hits the ground as fast as a pistol bullet.

[1:11](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=71) Its entire fifty-eight-foot length goes into the pavement in one-sixteenth of a second. The tail is still flying at full speed while the nose is already gone.

[1:22](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=82) It carried about three hundred and sixty megajoules of energy.

[1:25](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=85) That's like five hundred and fifty cars hitting a wall at sixty miles an hour all at the same instant.

[1:32](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=92) The airframe doesn't break into big pieces. It shreds.

[1:35](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=95) In the simulation, fragments fly out at seventy-five to three hundred and twenty miles an hour. From the dashcam, one pixel covers about two inches. Many of these pieces are smaller than a pixel, and they cross up to sixteen feet between frames.

[1:51](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=111) To a thirty-frame-per-second camera, they aren't pieces at all.

[1:54](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=114) They're a smear or nothing. The NTSB says debris is spread across roughly half a mile and that there's some evidence the jet began breaking up before impact.

[2:05](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=125) This reconstruction assumes it hit in one piece.

[2:08](https://www.translate.mom/transcript/B9DyRnzlpOWm/en/learjet-n722bd-crash-on-military-trail-3d-reconstruction?t=128) What the dashcam recorded as three blurry frames was the near instant total destruction of a nearly ten-ton jet. What it didn't show was the tragic death of the nine people on board.
