The edge of the Horsehead nebula, where it touches the empty space outside it, is rich in carbon. It describes how carbon flows between living organisms, and the ocean, atmosphere and rock of our planet, and is driven by the energy from our sun.
By every American Navy fighter squadron flew the F4F. Collection Item Long Description: But during the dark months after Pearl Harbor, Wildcat pilots stood firm, held the line, and stopped the Imperial Japanese military air forces when they seemed invincible.
By the mids, the fast, low-drag monoplane was rapidly replacing the biplane in every major air arm in the world.
Schwendler created the first Grumman monoplane fighter, the XF4F Extended development trials delayed production and led the Navy to award a production contract for the first United States carrier-based naval monoplane to the Brewster Aeronautical Corporation.
Brewster built several hundred F2A Buffalos but Grumman engineers reworked the XF4F and came up with a greatly improved model that outperformed the Buffalo. The Navy accepted the Grumman design and awarded contracts to the company to produce thousands of F4F fighters.
Wildcats went to the U. Navy and Marine Corps and to the French, who desperately needed military aircraft.
It became the first U. In the Pacific during DecemberAmerican Wildcat pilots finally met the enemy as they tried to defend Wake Island.
The remaining four fighters flew day and night, fighting heroically for two weeks, breaking up many air attacks and sinking a cruiser and a submarine with pound bombs before the last two Wildcats were destroyed on December That day, the Japanese landed on Wake.
Despite similar losses throughout the Pacific, pilots flying this tough fighter destroyed an average of seven enemy aircraft for every Wildcat lost.
To make room for Hellcat production at the Grumman plant, the company transferred Wildcat manufacturing tools and equipment to the Eastern Aircraft Division of General Motors. After thirteen months of service, the Navy struck the fighter from the active roster and placed it in storage.
It was transferred to NASM in In the Grumman Aerospace Corporation agreed to restore the Wildcat for exhibit in the new National Air and Space Museum building set to open in Former and active members of the company worked on the fighter -- many of them had built Wildcats for Grumman during the war.
Early in the Wildcat emerged, looking like new and in nearly flyable condition. It wore new paint that duplicated the U. Navy blue-gray camouflage used early in the war. The markings were patterned after an FM-1, aircraft number E, that operated from the escort carrier U.
At some time during storage, a major component went missing from this FM-1, the nose cowl ring that covered the front of the engine. This discovery led NASM officials to search for a spare.
When the Grumman craftsmen received it, the ring cowl was still riddled with bullet holes incurred during the Japanese assault.
This historic component perpetuates the memory of those Marines who fought and died on the island. The Wake Island Memorial reads, "dedicated to the gallant Marine, Naval, Army, and Civilian personnel who defended Wake against overwhelming Japanese invasion armadas, 8 thru 23 December Students attend a physics practical for one afternoon once every two weeks.
The primary aim of the class is the development of experimental skills, which are important to all professional physicists. The second aim of the practical session is to illustrate ideas and concepts in physics.
