But remember - He's not a pilot but have read the pilot manuals.I also like the way he picks which parts of the manuals (or which sentences ) he is going to use and which he is going to ignore.
I *almost* said "have a look in the mirror", but held back.A lot of humor in this thread.
I think I got my biggest laugh when P-39 expert ask for the definition of a troll.
I do like the way the P-39 "escorts" clear the airfield fence, get the gear up, switch to the drop tank and head for Germany.
at some point in 1943 the P-47 groups changed number of aircraft per squadron to 25 aircraft. Or 75 planes for a 3 squadron group. even if not all planes are flying let's call it 50 planes operational on a given day. At 15 seconds between planes that is 12.5 minutes, at 20 seconds between planes that 16.7 minutes.
Using the "experts" flight plan the lead plane/s are at about 15,000ft and 50 miles from the airfield when the last plane/s take off.
This is actually brilliant planning as we don't have to worry about the fuel used in formation flying. There is NO formation. Just a bunch of planes in ones (mostly) and twos (occasionally) strung out over 50 miles winging their way into enemy airspace.

Why not paint them bright colours with bands, stripes and circles any bomber box wandering aimlessly in the North Sea could form up and act as top cover.I do like the way the P-39 "escorts" clear the airfield fence, get the gear up, switch to the drop tank and head for Germany.

What the barreling f**K?!?! The P-38 has TWO engines? Why didn't anybody tell me this earlier?Yes, the P-38 was a twin meaning that two engines must be started (separately) and two sets of propeller and mag checks must be undertaken (separately).
Yeaaah, see here's the thing, Bill can, probably off the top of his head, give you a rough estimate for a mission profile and be more accurate than someone reading a pilots manual and running figures for hours. If he actually devoted time to it, you could bet the house it'd be correct.*SNIP*
Bill can compute his own crazy flight plan. I have computed numerous flight plans on here for the P-39 and the P-47 and the information comes straight from the manuals. *SNIP*
The big failing in the British "conspiracy theory" is that the British didn't order the P-400 in the First place.I think your first point there is the crux of the matter. The Brits ordered the P-400 before any operational variant P-39 had flown. We have no idea what performance claims were made by Bell, although the chart provided earlier in this thread gives some indication that the pre-1941 performance estimates were ridiculously optimistic. Rather than the Brits deliberately besmirching the good name of Bell, it seems far more likely that Bell sold the Brits a bill of goods....and then failed to deliver on it.
Never been posted but the same instructions are indicated on the Flight Operation Instruction Charts and I bolded "CHARTS" to indicate more than one. The instructions are quite clear but mentions nothing about fuel consumed during climbs, so I guess we have to omit that consideration! Thanks for posting!I do not know if the following has been posted in this thread before, but for what it is worth:

Have fun.

It was something about the 1949 Studebaker's goofy back window.Does anyone remember what this thread was originally about? What was being discussed about the P-39 that the thread was to answer?

The French did and Britain took over the order when France fell. Britain also took over just about ALL French orders for defense goods when France fell.
Major revisions to the French specification in the summer of 1940 was pretty much to get the plane flyable to British standards, like change the direction of throttle operation, substitute non metric instruments, make sure British and American guns could be used and not French supplied guns, shelves/brackets for British radios and so on.
This was done BEFORE the Americans ordered any P-39Ds or changed the last of the P-39Cs to Ds. It kind of locks the British into a certain configuration.
The "expert" seems to think you can just change things at a whim. It may take dozens of drawings to made to change the heating system. You need drawings of even such things as a knob and control cable to open a door in a duct. Let alone drawings of the duct. The more changes you make the longer it takes to get your finished airplanes.
There were two more specification revisions, one several months before Lend lease was passed and one several months after.
Bell had several opportunities to revise the performance specifications, they didn't.
Were the British even offered the new heating system?
Unless there are documents showing the British turned down the new heating system and keeping the gas fired heaters then this portion of the debate should be put to rest.
Coincidence is not proof.
I have asked for this several times before, there is a massive difference between specifying that the cabin and guns should be heated, and accepting a manufacturers proposal to do the same, to "saying use this heater in your plane". The Hurricane and Spitfire used ducted air systems, why would the British reject one?The big failing in the British "conspiracy theory" is that the British didn't order the P-400 in the First place.
