  • The grenade thing depends on the generation of grenade. Also depends on the country of origin. Assuming we are talking about the American M67 one you see in most movies, there are 3 different generations of safeties.

    Quick basics of an American grenade- the spoon is the handle looking thing that is sticking out the top and runs along the side. Under it in the head of the grenade is a spring that is always trying to push the spoon off its hinge and make it fly off, while then starting the fuse and the whole bang process. The safety pin (a codder pin with a ring on one side to pull on) runs through the head of the spoon and is held in place simply through binding into its hole/channel by tension provided by the spring. For a little bit of extra safety the end of the pin sticks out about a quarter inch and is bent for a little, but easily straightened and pulled out with the ring (look up a picture and you will see what mean).

    The old ones were just the safety pin held in place by the spring/spoon mechanism. But if you had excessive vibration or just enough pressure and you had pre-straightened the safety for pulling ease, it would negate the spring pressure and the safety pin could slip in and out with ease (thus easy to pull with teeth for Rambo effect). People didn’t trust it, so it was typical to then use electrical tape to hold the spoon down wrapped around the full body and then a bit extra folded back to make a quick pull tab. To throw: pull e-tape, pull pin, throw. The army then added a secondary safety to the safety. It was this secondary safety clip that held the spoon down to the head, providing constant tension and stopping the vibration loosening issues. They were also intentionally designed to have to get pulled off in opposite directions. To throw: (I am left handed) sweep safety clip left, pull pin right, throw. This was in my opinion the best setup and my favorite of grenade generations. Apparently this was about 50/50 with other others. So the army then came out with their third generation, the “confidence” thumb guard thing. It is a metal flap switch that locks/latches the safety clip onto the pin ring. I thought it was dumb. Most people hate it. But credit where credit due- it is impossible to fuck it up. Now to throw: thumb/sweep up on confidence latch, sweep left on safety clip, pull right on pin, throw.

    I am a fan of all good sci-fi, regardless of the time it was made or the limits of the budget. This one is on the list. I will warn others as it has been pointed out- very rape centric plot and story beats. Be sure to watch it with a good level of suspension of disbelief and understanding of the setting. Beyond that, it is one of the best post apocalyptic stories out there and I wish it was redone with more plot, tighter story, and less rape related with the exception of the Topeka plot line. Highly recommend for anyone who enjoys old sci fi or post apoc.


  • You would be surprised. If you worked a decent job early in life, moved up the ladder, retired as upper middle class making $250k-ish, it is kind of expected to have about 2-3 mil in your retirement. Hell, if you work a half way decent government job and invested wisely your entire life and didn’t have stupid amounts of debt, you should have about a mil in retirement.

    1 mil in retirement gives you about 5,500 per month at a growth rate of 6%, withdraw rate of 3%, and annual inflation at 3%. The current recommended retirement is a little under a mil.

    As far as retirement funds counting as tradable assets, that is how your 401k accounts work. It is literally a stock market account. The question comes down to when the tax is paid, pre or post withdrawal. In a roth IRA you pay the tax coming in. In a traditional IRA you pay tax when the money comes out. Either way, as long as the money stays in the account you can make it liquid, put it in a stock, bond, mutual fund, whatever you want as long as the account can do it; but in the end it is in a trading account and short of the cash in there, it is a tradable asset.








  • Fun fact, in the book Jurassic Park and in the initial script, there was a river boat sequence. It was extensively planned in preproduction and teased as part of the plot. This was spread to the other ‘tie-in’ merchandise and park ride. This is why the universal studio ride is a water ride and why games that timed their release with the movie had river sequences. But as we all from the future know, it never happened. Budget overruns and shooting delays lead to script rewrites to cut out that sequence.



  • Seriously. We are talking about tire tread compared to weight. Both use multiple sizes of tire depending on the year/model. There are a few that overlap in diameter to get the closest to comparison but they still have a very different width. We are talking about a 235/35R18 vs a 235/75R18. That is a huge difference in wall height/aspect ratio and changes how the tire gives under power. Those numbers massively change depending on model as well. Something like an f150 raptor could have a 315/70R17, almost a foot wide. So comparing just the weight and saying they are close enough is far from a fair comparison.





  • While any aircraft sent to ukrane is nice, I sure hope they aren’t paying much for them. That airframe is about 60 years old with the last major design overhaul in 1990 and its last electronics upgrade in 2000. They would be better off buying F15e’s or even the new f15ex. He’ll, even getting some last Gen f16’s or f18’s over there would be as good or better, but cost probably more. The f15 though is probably the best multiroll jet for the cost.

    Now, if we are talking about sending some OG Mirage 2000 fighters over there, then that sounds like the ultimate white elephant gift France could give. The US could sent some F4 phantoms over while we are at it.

    The big news I the training of 4500 pilots. That is huge. If they could do that, then the mirage 2000 could basically turn into their base fighter trainer and use it as the training wheels to get the new pilots experience and into bigger and better things.
