Interstate 30

Interstate 30 (I-30) is an Interstate Highway in the southern United States. While most interstate routes ending in zero are major cross country routes, I-30 is a comparatively short regional route serving only two states. I-30 runs from I-20 west of Fort Worth, Texas, northeast via Dallas, Texas, and Texarkana, Texas, to I-40 in North Little Rock, Arkansas. The route parallels U.S. Route 67 (US 67) except for the portion west of downtown Dallas (which was once part of I-20). I-30 intersects with only two of the 10 major north–south Interstates (I-35W, I-35E and I-45) and also with the major Interstate routes I-20, and I-40. I-30 is known as the Tom Landry Freeway between I-35W and I-35E, within the core of the Dallas–Fort Worth metroplex.

Route description

I-30 is the shortest two-digit Interstate ending in zero in the Interstate system. The Interstates ending in 0 are generally the longest east–west Interstates. It is also the second shortest major Interstate (ending in 0 or 5), behind Interstate 45.

Yakovlev Yak-3

The Yakovlev Yak-3 (Russian language: Я́ковлев Як-3) was a World War II Soviet fighter aircraft. Robust and easy to maintain, it was much liked by pilots and ground crew alike. It was one of the smallest and lightest major combat fighters fielded by any combatant during the war, and its high power-to-weight ratio gave it excellent performance. It proved a formidable dogfighter. Marcel Albert, World War II French ace, who flew the Yak in USSR with the Normandie-Niémen Group, considered it a superior aircraft to the P-51D Mustang and the Supermarine Spitfire. After the war ended, it flew with the Yugoslav and Polish Air Forces.

Design and development

The origins of the Yak-3 went back to 1941 when the I-30 prototype was offered along with the I-26 (Yak-1) as an alternative design. The I-30, powered by a Klimov M-105P engine, was of all-metal construction, using a wing with dihedral on the outer panels. Like the early Yak-1, it had a 20 mm ShVAK cannon firing through the hollow-driveshaft nose spinner as a motornaya pushka, and twin 7.62 mm synchronized ShKAS machine guns in cowl mounts ahead of the cockpit on the fuselage, but was also fitted with a ShVAK cannon in each wing. The first of two prototypes was fitted with a slatted wing to improve handling and short-field performance while the second prototype had a wooden wing without slats, in order to simplify production. The second prototype crashed during flight tests and was written off. Although there were plans to put the Yak-3 into production, the scarcity of aviation aluminum and the pressure of the Nazi invasion led to work on the first Yak-3 being abandoned in late fall 1941.
