At 22:00 ish the expert is wrong. Its basic Newtonian physics. A falling bullet moving laterally is following a ballistic trajectory. - Very simply it still has some of its original inertia and can be flying a lot faster than terminal velocity.. (The MythBusters then go on to argue this themselves..)

Who uses a timestamp and goes "ish" like, "maybe its there, go find it". The whole point of a timestamp is to point to your reference. Thats not even lazyness, thats deliberate ignorance.

@@Damaged7 Oh dear.. I made an estimate of the time and typed it in. Double checking the thing it made more sense taken 30 seconds earlier at say 21:30. What you failed to understand is that you can type a time estimate in - hence the warning word 'ish'.

46:00 - Ouch, that's like saying that if you floor the accelerator of your car and it accelerates from 0 to 10 (mph/kph, doesn't matter) in x seconds, it will accelerate by 10 _every_ x seconds until it reaches it's top speed, completely ignoring any factors that slow it down as it's speed increases until the very second it hits top speed...

I can't imagine why they wouldn't have had enough sense to take a couple metal detectors out to the desert to find those bullets.... 🧐

Because metal detectors detect magnetic metals which bullets are not.

@@MrMarinus18That's wrong. The material must be magnetic or conductive to be detected by a metal detector.

Bullets are lead. If it has a jacket it’s copper and lead. Copper is non ferric and lead is a transitional metal. Neither are detectable with a metal detector.

@@BlitzMekanika 1. Metal Composition: Bullets made of metal or with a metal casing are detectable. For example, bullets with a copper jacket or steel core will be easier to detect. Lead, while less conductive, can also be detected by a metal detector, though it may be less easily detectable than other metals. 2. Size and Depth: The size of the bullet and its depth in the ground or within an object will affect detection. Larger and more shallowly buried bullets are easier to detect. Smaller bullets buried deeper may be harder to detect, especially with lower-end metal detectors. 3. Type of Metal Detector: The sensitivity and capabilities of the metal detector play a significant role. Higher-end metal detectors designed for detecting small objects will have better success in detecting bullets. 4. Environmental Factors: Soil composition, moisture, and the presence of other metallic objects or mineral content can impact the effectiveness of the metal detector.

@@BlitzMekanikait’s called a metal detector, not iron detector, isn’t it? its working principle is based on inductance, not magnetism. I own a metal detector and have found bullets with it

Yeah, a bullet falling on its side, even at terminal velocity, doesn't have enough penetration capability to kill a human. But if the bullet has enough horizontal velocity to continue flying with it's tip pointed forwards/downwards (in it's ballistic trajectory), it experiences less aerodynamic drag and can easily penetrate a human skull. After all, that is the purpose they were created for.

A bullet fired straight up will reach a point where it loses all of its original inertia and come to a full stop before tumbling back to Earth at its terminal velocity under the influence of nothing but gravity and air resistance. A bullet fired up at an angle will lose all of the vertical component of its original inertia but will retain all of the horisontal component, less air resistance, at which point it will NOT come to a full stop but will maintain a ballistic trajectory i.e., its terminal velocity PLUS the horisontal component and may thus retain sufficient velocity, depending on the firing angle, to be lethal. It is simple, fundamental physics.

It only takes 39 foot/pounds of energy to penetrate human skull, or half inch plywood. This is stated and demonstrated on several gun channels.

En las celebraciones de oriente medio,por ejemplo,es normal ver grupos de gente disparando sus armas automáticas en grupo,y ráfagas.No parece que provoque heridas.Aunque habría que preguntar un kilómetro mas allá.😅
