Sobre os Me-109 usados por Israel, eram DETESTADOS pelos Pilotos: o motor era outro (e menor taxa de RPMs, piorando a já péssima estabilidade em operações de decolagem e pouso), as metralhadoras sincronizadas davam jam direto e cortavam hélices, ninguém queria voar neles.

Eles eram fabricados na Iugoslávia se me recordo bem. Havia grande diferenças para os dos Alemães.

Na verdade Tchecoslováquia, eles faziam com uma mistura de peças e motores Alemães e de outras procedências. A grande besteira foi botar motor de Bombardeiro :shock: no caça, que gerava um torque muito maior (torno a dizer, as características de decolagem do -109 já eram ruins, pela posição das "pernas" do trem de pouso), o que complicava ainda mais as operações de decolagem. Uma curiosidade: o problema com o propulsor era tão grande que interferia até na sincronização da Mtrs, a ponto de bem cedo os Israelenses aprenderem a, após atingir altitude segura, realizarem alguns disparos. Se a hélice fosse atingida (e volta e meia era) a ponto de comprometer a capacidade de voo, o cara pulava de paraquedas!

Mal terminada a guerra, temendo uma possível capitalização política da vitória aliada por membros da FEB, dada a contribuição desta à mesma, mesmo que modesta, decidiu o governo brasileiro desmobilizá-la oficialmente ainda em solo italiano.

A seus membros, no retorno ao país, foram impostas restrições, os veteranos não militares (que deram baixa ao retornar) foram proibidos de utilizar em público condecorações ou peças do vestuário expedicionário, enquanto os (veteranos militares) profissionais foram transferidos para regiões de fronteira ou distantes dos grandes centros.
Não tinha conhecimento disso, mas é coisa bem esperada do ditador Getúlio Vargas e asseclas.

Project Habbakuk: Britain’s Secret Ice “Bergship” Aircraft Carrier Project

In early 1940s, German U-Boats were wreaking havoc on Allied forces in the Atlantic Ocean, sinking ships and threatening to turn the tide of the war. As the Allies of WWII got desperate, one inventor working for the British Combined Operations Headquarters had an idea: a giant, floating, mobile and unsinkable island made of ice.

Inventor Geoffrey Pyke saw a giant floating ice ship as a natural option in the face of material limitations. Steel and aluminum were in short supply, but water was everywhere. And making it into ice required relatively little energy. So why not use ice instead of steel?

The solution came in the form of something that came to be known as pykrete: a mixture of wood pulp and frozen water. Wood provided reinforcement, making up for deficiencies in pure ice much like steel rebar helps concrete function in structural contexts. Pykrete would float well and melt more slowly. It could be machined like wood and cast like metal. Still, to keep it cold, a ship would need to be insulated and require a system of on-board refrigeration to keep it from melting.

In 1943, a prototype was commissioned. It would be constructed in Canada by conscientious objectors unaware of the project’s purpose. A 1,000-ton scale model measuring 30 by 60 feet was built on Patricia Lake in Alberta. It was kept frozen in the summer using just a single-horsepower motor, designed to show off the technology under real-world conditions.

A complete, full-scale vessel was to be ordered following a successful test.

The full-sized ship would need to have a range of 7,000 miles, support heavy bombers and be torpedo-proof. It was to be over a mile in length, weigh as much as 2.2 million tons and require as many as 26 electric motors to move and steer across the ocean.

In the end, Project Habakkuk was scrapped due to the changing war situation. New airfields had reduced the need for carriers and longer-range fuel tanks were helping aircraft fly further. The estimated price tag of 10 million British Pounds for the project was also deemed too high.

Still, the prototype proved its potential, even once neglected: it took three hot Canadian summers for the test vessel to completely melt. Its remains can be found at the bottom of Patricia Lake in Jasper National Park, marked by an underwater plaque.

pra tempos de guerra a ideia não é ruim.

Mas hoje creio que duraria menos devido aos verões mais quentes :P.

Já li sobre esse projeto, não funcionou tão bem assim, derretia mais rápido que o esperado, não era preciso derreter inteiro para comprometer a operação.

The World War II battle where Americans and Germans fought on the SAME side: Incredible true story of the fight to save an Austrian castle two weeks after Hitler committed suicide

The two sides fought off an SS bombardment at Castle Itter in Austria
They defended the castle and rescued high profile French prisoners
Former French presidents and prime ministers were kept prisoner
It was the only time Allied and German troops fought together

Sabaton tem uma musica sobre esta batalha :p.

Tb é bem interessante a luta de uma tropa alemã, nos ultimos dias da guerra salvando civis levando eles pro lado dos aliados mesmo sob uma situação praticamente impossivel.

Researchers find wreck of World War II cruiser USS Indianapolis

Billionaire and philanthropist Paul G. Allen and his researcher team have found the wreck of the famed World War II cruiser USS Indianapolis, which was lost on July 30, 1945.

The cruiser was found in the Philippine Sea, more than 18,000 feet below the surface, with the number 35 on the hull as a first confirmation.

Around 800 of the ship’s 1,196 Sailors and Marines survived the sinking, but after four to five days in the water – suffering exposure, dehydration, drowning, and shark attacks – only 316 survived.

The wreck was located by the expedition crew of Research Vessel (R/V) Petrel, which is owned by Microsoft co-founder Allen, 5,500 meters below the surface, resting on the floor of the North Pacific Ocean.

“To be able to honor the brave men of the USS Indianapolis and their families through the discovery of a ship that played such a significant role in ending World War II is truly humbling,” said Allen. “As Americans, we all owe a debt of gratitude to the crew for their courage, persistence and sacrifice in the face of horrendous circumstances. While our search for the rest of the wreckage will continue, I hope everyone connected to this historic ship will feel some measure of closure at this discovery so long in coming.”

Indianapolis was lost in the final days of World War II when it was torpedoed by a Japanese submarine in the early morning hours of July 30, 1945. The Indianapolis sank in 12 minutes, making it impossible to send a distress signal or deploy much of its life-saving equipment. Prior to the attack, the Indianapolis had just completed a secret mission delivering components of the atomic bomb used in Hiroshima that would ultimately help end the war in the Pacific.

“Even in the worst defeats and disasters there is valor and sacrifice that deserves to never be forgotten,” said Sam Cox, director of the Naval History and Heritage Command. “They can serve as inspiration to current and future Sailors enduring situations of mortal peril. There are also lessons learned, and in the case of the Indianapolis, lessons re-learned, that need to be preserved and passed on, so the same mistakes can be prevented, and lives saved.”

Others have searched for Indianapolis in the past. Among the elements that made this effort different was Allen’s recent acquisition and retrofit of the 250-foot R/V Petrel with state-of-the-art subsea equipment capable of diving to 6,000 meters (or three and a half miles).

The other key factor in the discovery was information that surfaced in 2016 when Dr. Richard Hulver, historian with the Naval History and Heritage Command, conducted research that led to a new search area to the west of the original presumed position.

Hulver’s research identified a naval landing craft that had recorded a sighting of Indianapolis hours before it was torpedoed. Using that information, the research team developed a new position and estimated search, which was still a daunting 600 square miles of open ocean.

Allen-led expeditions have also resulted in the discovery of the Japanese battleship Musashi (March 2015) and the Italian WWII destroyer Artigliere (March 2017). His team was also responsible for retrieving and restoring the ship’s bell from the HMS Hood for presentation to the British Navy in honor of its heroic service. Allen’s expedition team was recently transferred to the newly acquired and retrofitted R/V Petrel specifically for continuing exploration and research efforts.

The 13-person expedition team on the R/V Petrel is in the process of surveying the full site and will conduct a live tour of the wreckage in the next few weeks.

Their work is compliant with U.S. law, respecting the sunken ship as a war grave and not disturbing the site. USS Indianapolis remains the property of the U.S. Navy and its location will remain confidential and restricted by the Navy. The crew of the R/V Petrel has collaborated with Navy authorities throughout its search operations and will continue to work on plans to honor the 22 crew members still alive today, as well as the families of all those who served on the highly decorated cruiser.
