    Bomber Command, World War II (1939-45); and the lies and corruptions of Geopolitics

    There has been a very good, detailed accounting analysis of Bomber Command. The infrastructure costs were staggering. I have the article somewhere, but digging it out is going to be a nightmare.

    Armored Glass

    I don't think anyone had armored glass that could survive a 20mm round. MG damage: Spitfire Mark I Windscreen T.O. No. 01-65BC-1 "P-47 Thunderbolt Pilot's Flight Operating Manual" Section I "Description", 1. "Airplane", d. "Pilot Protection" (1) says: ARMOR. - Front and rear armor protection...

    Armored Glass

    Why does he think it might be German? Any chance you can find faintly engraved markings? Can you post a photo of the back of the yellowish piece? It looks as though the size of the laminated layers are different on the front and back. Is there anything that might indicate which side is down?

    Fairey Swordfish, A Plane Reborn. The Aircraft That Crippled The Mighty Bismarck

    That dude does terrible videos. Be sure to thumbs-down if you watch one--otherwise, the algorithm promotes the video to everyone else. That's the problem with an algorithm that just counts views.

    Two mystery items

    The one on the right is some sort of anti-vibration mount, but the hook has me baffled. Is the lens convex (magnifying) or just flat?

    eBay: Bloch Fighters

    It's a 3-bladed LeO C.30, a license-built variant of the Cierva machine. The French army had great hopes for using them for artillery observation, but was disappointed. The French navy received some for anti-submarine use shortly before the May attack. As an artillery observation aircraft it...

    Why did first generation jets with fuselage mounted engines have such long jet pipes?

    Lack of all-flying tails? With the CoG and CoL so close to the elevators, they don't get much of a lever advantage. For aircraft without hydraulic boost, this would be even more if a problem.

    What If Tetraethyl Lead additives were banned in the 1920s? Effects on WW2?

    All I know is that the nearest gas station to work has E85 and it was less than half the price of regular unleaded a few months ago. (With falling gas prices it's probably "only" 60%.) Anyhow, talked to a guy who was filling up his Flexible Fuel Vehicle Ford. His mileage on E85 was only about...
