The Importance and Functionality of Black Boxes in Transportation
TLDR Black boxes, or flight data recorders, are crucial components in airplanes, trains, and cars that record various data and sounds to help determine the cause of crashes or accidents. They undergo rigorous testing to ensure durability and are designed to survive extreme conditions, with the crash survivable memory unit being the most vital component.
Timestamped Summary
00:00
Black boxes, or flight data recorders, are not actually black and were named either because the original ones were black or because they would become charred in the wreckage and turn black.
04:47
Black boxes are actually a group of components that record flight data and cockpit sounds, and they are meant to survive plane crashes in order to determine what happened.
09:16
Black boxes are installed in airplanes and consist of a flight data recorder, cockpit voice recorder, and crash survivable memory unit, with the latter being the most important component that needs to survive a crash and is designed to withstand extreme conditions; they record various sensor data and cockpit sounds during flights and are located in the back of the plane to increase their chances of survival in a crash.
13:21
Black boxes record various types of data during flights, including cockpit sounds and sensor data, and there are websites that have recordings and transcriptions of the last moments before a plane crash.
17:36
The crash survivable memory unit of a black box is made up of three layers of materials, including an aluminum housing, dry silica insulation, and an outer shell made of stainless steel or titanium.
21:43
Black boxes undergo several tests, including crash impact, pin drop, static crush, fire, deep sea immersion, saltwater submersion, and exposure to various fluids, to ensure their durability and ability to withstand extreme conditions.
26:18
Black boxes are tested to withstand deep sea and saltwater immersion, and have an underwater beacon that sends out a ping every second for a month to help locate them in case of a crash, and even if the ping stops, the black boxes can still be found and their data analyzed.
30:26
Black boxes are used in airplanes, trains, and cars to piece together information and determine what happened in the event of a crash or accident.

Kosher salt is used to draw blood out of meat in accordance with Jewish dietary laws, but it is important to note that salting the meat alone does not make it kosher; the animal must also be kosher and killed in a specific ritual called shecting.
38:26
The basics of kosher meat and Jewish dietary laws are too complex to cover in an email or single episode, but a book called "Kosher for the Clueless but Curious" by Simon Episdorf provides more information.
