pretty planes


The 737 was first designed as a STOL aircraft. STOL - Short Takeoff and Landing

Tha's a picture of the 737 - 100 at the top of the photo.

It was designated as the 737 - 100, then came the - 200, then the 737 - 300 with new CFM engines, which were quieter than the JT8D's that they replaced. In addition, they were more fuel efficient and powerful, due to newer technology.

The bottom picture is of the 737 - 800.

The 737 has come in a LOT of different models starting with the 737 - 100 and now with the 737 - 900. Then there is also the classification of MAX, as well.

So, you can have a 737 - 800 or a 737 - 800MAX. Same with the 737 - 900.

Cool plane - P-61 Black Widow.

http://johnweeks.com/p61/p61_large.jpg

The Northrop P-61 Black Widow, named for the American spider, was the first operational U.S. military aircraft designed specifically for night interception of opposing aircraft, and was the first aircraft specifically designed to use radar.[2][3] The P-61 had a crew of three: pilot, gunner, and radar operator. It was armed with four 20 mm (.79 in) Hispano M2 forward-firing cannons mounted in the lower fuselage, and four .50 in (12.7 mm) M2 Browning machine guns mounted in a remote-controlled dorsal gun turret.

That top turret was a problem unless it was facing forward.
