Being a Boston guy, England isn't exactly my buddy but WW2 was a great alliance, the Thames has always fascinated me, idk why, it's got tides ? But it's a river, I've since looked up why and how it works, it's the first thing I imagine when I think of England.🇺🇸🇬🇧

I have a Hardback DORLING KINDERSLEY DK EYEWITNESS GUIDES Book of TRAIN. Discover the story of railways - from the days of steam to the high - speed, sophisticated trains of today. In association with THE NATIONAL RAILWAY MUSEUM.

Wow.

Thank you! Best video/presentation I’ve seen of the barrier. An amazing feat of engineering! 🚢🌊

The Tizard Mission is what tipped the balance in the Atlantic. They carried with them one of the few Cavity Magnetrons in existence at the time. Now back then, they were made with precision machinists, a time and labor consuming process. Numberic machining was not in existence at the time. But when the Americans took one look at the magnetron, they gather together, and came to a most singular answer for the Mission team:Mass Production by stamping. Instead of making them with machines, they would STAMP out layers of components of the unit, then assemble, and solder/braze via baking in ovens, making them whole. All without the fussing over and worry about the unit not being in spec, because the layers were ALMOST always in spec! Spot checks would ensure the stamping of the blanks into the layers of the unit were proper and perfect. If it got out of spec, dump the batch, put another set of dies in, destroy the old set, and keep on churning out cavity magnetron components by the dozen every hour. This mass-manufacturing technique developed and perfected by the GE team, caused massive numbers of centimeter radars to be available for the sub-hunters.

So Rotterdam has a movable barrier that lets the whole river be used by boats, but the British limited to 200 feet, 60 meter wide boats?

Really come on you know that this net zero is tosh ... Silly fools

Any further updates, now we are in 2023?

Excellent presentation , wishing you the best speed and ‘all aboard’ forward momentum with this oh-so-validating local initiative

There are quite of these in my neighborhood and none of them have names out front. Nobody who knows who owns them and they are terrible neighbors.

14.14 "giving the technology to the Americans was absolutely essential at this time because we didn't have the capacity to manufacture these devices in the quantities required"

Excellent and highly informative video. Thank you.

Thank you. Seems like a good summary of available options, whether we like them or not.

Great, informative video, thank you

This is a very informative presentation. Well done and thank you.

Wonderful lecture! Thank you so much!

Excellent!! I so appreciated the level of detail and the clear explanations provided.

Excellent information. Thank you.

Well done. Thank you!

My father was trained on the ASV II radar simulator set up by Watson-Watt at RAF OTU 31, Debert, Nova Scotia. His feeling was that if one truly was properly trained how to adjust and utilize, ASV II was more capable over a longer range than what the specifications indicated.

I was navigator on last RNZAF Sunderland flight April 1967. The ASV 6C radar could detect contacts at night at 3 nm which usually when we charged in at 300 feet and illuminated with the Leigh light turned out to be seabirds resting on the sea.

The Lockheed PV-1 Ventura was the first American airplane to come off the assembly line with radar already installed. Used by the Americans in the Pacific and Alaska, and by all of the Commonwealth countries as anti-submarine and coastal patrol. Ventura Memorial Flight Association RCAF 2195/NAVY BUILD#33315/CF-FAV

I worked on surveillance and tracking radars in the MOD for years most of which was 50's tech so I saw quite a few Magnetrons big and small, (even water cooled !). So although this video slightly pre-dates my activities it was very interesting to me.

Excellent video, thankyou very much. I've just finished reading 'The bombers eye' which compliments this video from a bomber command perspective.

I agree wholeheartedly, wonderful video and presentation!

Magnificent, thankyou Sir!

This was a truly vital element in defeating Nazi Germany. May the men and women who developed viable radar equipment rest in peace knowing their contribution to humanity.

Death by PPT bullet point

Maybe Boris Johnston would support the plan?

The 4th Industrial Revolution is not an HMG creation. This comes from Klaus Schwab and the WEF. Engineers do not need to be told how to or commanded to innovate. In addition Klaus Schwab may have qualifications in engineering but he does not have real world experience of making or innovating anything. His book 'COVID-19: The Great Reset' is a dystopian nightmare. UK Engineering has suffered from lack of interest and understanding. James Dyson found this as did Frank Whittle and many other innovators. Also, Matt Ridley is not an engineer so I'm not sure how he can describe how John Harrison or Tommy Flowers innovated for example. Innovation can be gradual but also fast and disrupting. The Colossus computer and the wooden Mosquito aircraft were created in a very short time, and in the case of the Colossus, this was the work of one man. On top of all this there is the fashionable fixation with diversity of race and gender. Overtly encouraging and employing racial or gender quotas is wrong and ultimately divisive and will not lead to great innovation. How did the UK manage to innovate the amount that it did during the 19th century?

That was a terrific presentation! Thank you for giving it to us!

Marvelous video with lots of detailed information. Thank you.

Thanks for a very interesting video. Excellent! 23:07 I never realised the number of casualties suffered by the allied fliers, very much higher than I'd expected.

Flt Lt Leonard Trigg RNZAF flying with Coastal Command was awarded the V.C. posthumourously on the word on the captain of the U Boat that he attacked and sunk although losing his life and that of his entire crew during the attack. His name is on the memorial wall of the Auckland War Memorial Museum in Auckland New Zealand.

My aunt worked for Ratheon here in the U.S. during the war .I remember her telling me how the engineers would heat their lunches using this technology.

Excellent description of early RADAR ops. I was always wondering how those stange aerials on the nose could be used as RADAR's. Now I know.

Interesting lecture! Must investigate this group further as aside from my interest in aircraft I'm a UK based engineer (well, engineering manager these days) who studied communications and microwaves a very long time ago for my degree.

This man makes a very interesting subject sound like he is reading his shopping list. The subject matter is great, the presentation is very poor. two tins of cat food, a loaf of bread, half a pound of mince, low fat mince of course, strawberry jam and a sliced white loaf of bread, anal lube and a butt plug.

Quite why Britain’s government is so vexed over this issue that it feels necessary to commit the nation to expensive changes that will make no practical difference to the world in general is hard to establish. While I accept climate change appears to be accepted, the reality of the situation is altogether less certain, all the more so as much of the underpinning for this acceptance relies on propaganda and out right lying about what the situation was 50 to 100 years ago, fraud that works it way into modelling of what we might expect. While there is nothing wrong in improving our use of energy, the route we are going is fraught with difficulties and rather reliant on the transfer of what is spare from our continental cousins.

Thank you, an excellent video.

Thank you so much for this lecture. I've read many books on the Battle of the Atlantic so i already knew the ups and downs of the success rate. Now with your lecture I have a much better idea of the ASV systems and how the operated. I spent twenty years from 1970 to 1990 as a ASW aircrewman running passive and active sonars aboard the P-3 Orion, I was also cross trained on the radar system consisting of the APS-80 receiver/transmitter combined with the APA-125 indicator. We used it primarily for tracking merchant shipping and the MARKET TIME patrols during the Vietnam war. Thank you very much for detailing the RADAR systems used in the U-Boat war, I had always wondered exactly how they worked, indicators and tactics.

Excellent presentation. When the existence of the Metox warning system became known, were radar transmitters attached to ships in order to "spook" U-boats into submerging, thinking an unseen aircraft might attack them?

Liked and shared.

I quoted you on the "Open Mind" saw. Excellent goad for those too comfortable with themselves.
