Curtiss YP-37
The Curtiss P-37 was an American fighter aircraft made by Curtiss-Wright in 1937 for the US Army Air Corps. A development of the Curtiss P-36 Hawk to use an inline engine instead of the radial engine of the P-36 the fuselage was lengthened and the cockpit moved back. A small number of YP-37 aircraft was built for Air Corps evaluation. The expected top speed was not achieved and the project terminated in favor of the Curtiss P-40. Design and development In early 1937, after realizing the P-36 Hawk was inferior to more modern European designs, the USAAC ordered Curtiss to adapt one P-36 to the new liquid-cooled turbo-supercharged Allison V-1710 The Allison V-1710 aircraft engine designed and produced by the Allison Engine Company was the only US-developed V-12 liquid-cooled engine to see service during World War II. Versions with a turbocharger gave excellent performance at high a .... The prototype Hawk was fitted with a turbo-supercharged Allison V-1710-11 as the ...

Papyrus 37
Papyrus 37 designated by 𝔓37 (in the Biblical manuscript#Gregory-Aland, Gregory-Aland numbering) is an early copy of the New Testament in Greek.

Greco-Egizi 208, dated 256 CE).Philip W Comfort and David P Barrett. ''The Text of the Earliest New Testament Greek Manuscripts''.

Phosphorus-37
Although phosphorus (15P) has 23 isotopes from 25P to 47P, only 31P is stable; as such, phosphorus is considered a monoisotopic element. The longest-lived radioactive isotopes are 33P with a half-life of 25.34 days and 32P with a half-life of 14.268 days. All others have half-lives of under 2.5 minutes, most under a second. The least stable is 25P with a half-life shorter than 30 nanoseconds.
