More questions than answers ...

[Scooby]

I built a Compass Rose for the Army a few years back. (Many actually) Concrete with NO steel in the structure (for obvious reasons) and a 6" Brass cylinder in the center. Army engineers did the "TRUE" cardinal headings, for helicopters, probably never used but it was a good contract. Always wondered what was so important about the center brass pin? Surely being off didn't matter that much plus how close to centering the aircraft could one get?

I am sure the army used it. We no longer mark the rose with lines or headings, we put a second person out with a survey compass and he lines up on the aircraft/helicopter. We then have a signalling system to confirm our heading. Whatever heading is signaled to us is what we base our adjustments on.

On the inside we give the pilot the heading we would like him to taxi to or land on.

The most important part of the site is that it is surveyed and there isn't anything in or around it that will disturb the calibrations.

What's the plane on the left of the Mustang? ... I've seen one before, but I can't recall off hand.

A B-17 doing one heck of a balancing act. What's going on here? Photo only states: "Ridgewell - 381st BG"

Airfield transport tow dolly used in conjuction with airbags,Looks to be picking up on the jack points whereas the bags would be out under the wings.

This could be new to me. Did P-40B/C's have a smaller spinner than later versions of the P-40? Sure looks like it here. That 'is' an early P-40 spinner, is it not?

Here's a comparison (I think) ...

I think that's a young Herb Fischer in that F model.Could be filming God is my copilot.

.

back plate spinner of XP40 was 28" 3/4 dia, of P38: 28" dia and 30" for P40D and subsequent.(I hav'nt the size for P40B & C)
On this picture the difference between the spinner and front bulkhead(30" dia on P40D & later) seems more than 1" around, so it was not a spinner of P40 early or P38.
On the front bulkhead, the center hole at the bottom is at 11"3/4 of the center line spinner. This spinner is around 22" dia

Pretty sure the home team is Syracuse:


ETA: Also note the B-25 has continuous dihedral, making it one of the first eight built. Per Baugher, 40-2165 was around until January of '45, and 40-2168 is still with us today, so that narrows it down to six possible a/c (40-2166, 67, and 69 through 72).

Take note that the Mustang is one of the two XP-51B prototypes converted from P-51-NA airframes by North American.

Would the aircraft next to the Mustang be one of the Curtiss P-36, Hawk 75 variants using a Radial engine? The exhaust looks almost like a FW 190 or Fury
set-up. Read where Curtiss tried various engines and streamlining to the radial variants.




oops, already answered, Curtiss XP60C

Anyone care to answer this? ... what type props are those on this B-25C-15?... yes their 4-blades, but what type aircraft are they from?

Cut down Martin B-26 props perhaps? Its an interesting look.

Is that the one prototype with the R-2800's?

[Blackbirdfan]

I guess it could be, the cowlings are different. Too bad the shadows are so heavy inside the cowlings.

Martin B-26 props were Curtiss Electric. Those depicted are Hamilton Standards.
