Reply to comment by Brandon432 in TIL that flight recorders must be able to withstand an acceleration of 3400 g for 6.5 milliseconds and that this is roughly equivalent to an impact velocity of 270 knots (310 mph; 500 km/h). by IchBinKoloss
I wouldn’t be surprised if the flight recorder itself was surrounded by some impact-absorbing material, like an air bag or foam material.

Reply to comment by badwolfdad in TIL researchers found that the global average temperature from 19,000 to 23,000 years ago was about 46 degrees Fahrenheit. That’s about 11 degrees Fahrenheit (6 degrees Celsius) colder than the global average temperature of the 20th century, per a University of Michigan statement. by Embarrassed-Mouse-49
Ice ages occur every 100,000 years or so, so we’re due for another one.
Edit: apparently some people here don’t like reading facts.
