Not quite antoni. Your source(s) are somewhat inaccurate on some points. In December 1939 No. 54 Squadron recorded the delivery of the following “Rotol Spitfires”: N.3097, N.3103, N.3104, N.3110, N.3111, N.3122, N.3124, N.3130, N.3160, N.3172, N.3174, N.3176, N.3183, N.3185...

Nice!

Good stuff Waynos. Excerpted from Flight, March 28, 1940: Full pdf of the article for the reading pleasure of the board membership: Fighter Station with the Spitfires in Scotland Anyone care to venture a guess as to the squadron? I’m thinking either 602 or 603, both based...

That’s fine Vincenzo, you’re perfectly entitled to hold and share your opinion, however, we will remain in disagreement as I find your position singularly unconvincing and it’s apparent you are likely too invested in your view to change it no matter the evidence. That said, I promise not to...

Hi Juha: There are scans to be found online from various authors that are in agreement with conventional wisdom, the majority viewpoint and with what you’ve read: Wood Dempster Rolls Royce Heritage Trust David Ross Alfred Price

Hi Gents: I had a look at RAF fighter Squadrons Stations as of December 1939 and came up with the following break down, principally taken from Fighter Squadrons of the R.A.F. by John Rawlings. Squadrons equipped with Hurricanes in the UK during December 1939: 3, 17, 32, 43, 46, 56, 79...

>If you go to RAF Fighter Command Index they list all the RAF fighter squadrons based in the UK. […snip…] So yes, every active Spitfire and Hurricane base was listed for 100 octane. Nice work Hop, that adds up nicely. I had a hunch that might be the case. Fwiw, just to supplement your...

>>Having secured what were considered reasonably sufficient quantities of 100 octane, Fighter Command began converting its engines to this standard in March 1940, allowing boost (manifold) pressures to be raised without the risk of detonation in the cylinders. This initial increase in maximum...

Hi gents: There’s quite a bit of interesting documentation about the Hurricane’s performance, 100 octane fuel use during the Battle of France, over Dunkirk and during the Battle of Britain, as well as combat reports and pilot’s accounts noting +12 lbs boost, pulling the plug, etc. at these...

Claidemore, I concur with your assessment and conclusion that logically follows. The implications deriving from the excuses are, in a word, scary.

Thanks Hohun!

>So my conclusion is that the Japanese Army was ahead of the Navy in most respects when it came to fighter design… Interesting assessment Hohun and one in which I concur. >Dan Brown on his website points out that the Japanese Army did not only copy the aircraft concept, but also modern...

I was browsing Spitfire the History and came across this information of a Spitfire 21 (LA188) which was equipped with a Mach meter and dived to Mach .89.

Attachment shows Werner Girbig’s listing of pilot casualties for Nov. 2, 1944: Dragondog’s important qualifier should be noted; those aircraft destroyed where the pilot bailed, ditched or crash landed without injury are, as apparently is often/usually the case with German losses, not listed.
