“ FLY HIGH AND LIVE - OXYGEN EQUIPMENT ” 1944 WWII UNITED STATES NAVY PILOT TRAINING FILM 71072

It never ceases to amaze me how engineers 'programmed' mechanical systems to work using engineering principles alone before you could just throw a little computer in something. Like the assembly that automatically controlled the cockpit air to oxygen ratio based on altitude by building a little thing that expanded and contracted based on atmospheric pressure. Nowadays something like this would be a sensor that controlled a valve that behaved according to a paragraph of simple code. But back then it required knowledge of physics and fluid dynamics and spring compression and all this other stuff to make just a simple system like that work. We're truly spoiled today.

Agreed I’m a tech guy and love all the progress, innovation, and advancements technology, digital systems, computers, silicon chips, etc have brought us. They made things incredibly easy and convenient. For example, I’m an Army veteran and the M1A1/A2 tanks have amazing technology The computer can calculate ballistic solutions based on crosswind, outside temp, ammo temp, vehicle cant and other factors Laser range finders five us range Technology is amazing Abrams can see in the dark with thermal sights and lead targets automatically. It helps with targeting and hit/kill probability However these things used to be incumbent upon the soldier The soldier suffers though as they lose the ability to do complex tasks like they used to. Not relying on a laser for finding a range We had stadiamteric sights to find ranges or stereoscopic sights in the old days but they required knowledge Gunners learned to use “Kentucky windage” on tanks - you knew you gun and vehicle so well you could estimate range, lead, etc There is a huge difference between the Abrams M1A1 and A2 The A2 has all digital computer systems whereas much of the instruments and gauges are analog in the A1. Things like the fuel gauge, oil temp, and speed are analog needle gauges on the A1. The A2 has all the info and data on LCD screens. While the A2 has many advancements that help it is less reliant in the harsh field. If the systems go out and the crew has to rely on shooting, for example, without all the computerized help, they are at a huge disadvantage. I could go into the technical aspects but I’ll avoid that here for brevity. Anyway we all know computers and their programs are still done by humans That is why bugs and errors happen. We have become too reliant on them and have sacrificed many skills that are valuable Look at that Boeing airplane I forgot the nomenclature but due to bugs in its software it had several catastrophic crashes We should utilize and exploit technology but need to remember to practice alternate methods and MOs that don’t rely on our technology In fact we should always install override features so we ca bypass technology and computers from controlling everything. In fact, we have a lot of fiction that warns us of of AI and machine learning that bite us in the arse. We should heed those warnings and make sure we can still be functional and self-sufficient in the event of technology failure. We have become too reliant on systems. Eh, I am not sure If I cogently gotten my point across. Enjoyed a few old fashioned drinks tonight but don’t know if my writing has suffered😆 Anyway, I digress... I get your point although I am not sure if my point was described well enough or can be comprehended😉

Yea the O² regulator is really very simple. It's got an aneroid barometer that opens O² valve in relation to altitude. And a check valve. That's its.

@@KenjiMapes Thank you for your reply sharing some of your experiences, sharing your knowledge about some of the equipment you worked with when you served, and your thoughts on the above. And thank you for your service as well! =)

@@angry_zergling Thanks man I can write a lot Some times I forget about all the shit I write I should actually blog more than write a bunch of shit in the replies that usually no one reads😆

[@LuciusZedaker]

Don't know where you get these great historical treats. Thanks!

They are Department of Defense films that have, until lately, been kept out of the public domain.

This was great video!!

Whoever you are, if you ever visit Oxford U.K. - the drinks are on me. This is a fabulous channel/page/whatever and I am a fan. 😊

The type 14 o² mask comes in 3 sizes. Small medium and Italian.

Omg so funny!! So funny so funny ! B ran ran rah! Wow what a great joke hehehe never-mind about all those people who have zero idea wtf your talking about. I’m not one of them, I swear…..

[@LawnPygmy]

This is a surprisingly interesting video.

From horse back to flying into the air, after American civil war it took 50 years in WW1 and 80 years in WW2.

Even though there's no oxygen cylynder attached this should be shown over and over to all those who don't wear their sanitary masks properly, and God knows there are far too many of them.
