If it averaged 6 kph on the trip back and took 4 hours, the distance of one way was 24 kilometers. If the trip there took three hours, 24 kilometers / 3 hours= 8 kph
He was carried on an aircraft carrier with his plane
Because they can't be sunk. Aircraft carriers were expensive and took a long time to build. The aviators who flew from them required specialized training. They were vulnerable to submarines. Dozens of submarines could be built for the cost of a single carrier. The crew of a carrier was as many men as in twenty or more sub crews. Carriers required a dozen or more ships of other types to protect them from submarines and aircraft. Carriers only have room for a limited number of aircraft. And those aircraft have to be relatively small, so they can take off and land in the few hundred feet of carrier deck - an area shorter than a football field. Because these aircraft have to be relatively small, they are limited in the amount of fuel they can hold, and in the amount of bombs and ordnance they can carry to the target. A WWII carrier aircraft could range out about 250 miles from its ship and be able to return after making its attack. All WWII carrier aircraft had to be single engine, and the heaviest could carry about one ton of bombs. A land airfield could be as big as the island. On Saipan and Tinian in the Marianas huge airfield complexes were built, each home to dozens of heavy, four engine bombers, which could carry tons of bombs two thousand miles and return. Islands do not move. In darkness or bad weather they can be found. Finding a carrier the same conditions in a vast expanse of ocean was not easy in WWII.
By individual carrier you can send you tax return to the correct address.
The Doolittle Raid of Saturday, 18 April 1942, was designed to be symbolic in nature. It would openly demonstrate to the Japanese & the Allies that the United States could & would strike back at the Japanese directly into their home islands. This raid occurred during a run of several months that the Japanese had a string of victories against the Allies. It signaled that the United States intended to bring the war to the Japanese. It was meant to boost the morale of Americans already fighting the Japanese, the American public, and the Allies (especially the Chinese). It was also intended to undermine Japanese propaganda and public support for the military leadership of Japan.The primary difficulty that the US military had to overcome:Because all US & Chinese land bases were too far away to use the US Army B-17 bomber, then…How do you get an aircraft carrier w/ aircraft close enough to Japan without being detected by the enemy?The mission analysis determined that it was virtually impossible to get an American aircraft carrier within 250 miles of the Japanese home islands without being detected prior to launching the strike, and then completely impossible to avoid detection after the strike hits Japan. This would endanger all US ships engaged in the raid. The further away from Japan that the aircraft could be launched on the strike, then the better the chance of the raiding ships escaping Japanese air & naval reactions. There was never any intention of the raid being a suicide mission for either the ships or the aircraft pilots.The US Navy carrier aircraft currently in service did not have the round-trip range to launch from a planned safe distance of at least 400 nautical miles. The only viable solution was to use twin-engine medium-range aircraft.However that posed its own challenges:How could a twin-engine medium-range aircraft take-off w/ a bomb-load from an aircraft carrier?If US Army aircraft are used, is there enough time for the crews to be trained to take-off from a carrier?Is it possible to lighten the bombers enough to allow for enough fuel & bombs that will not prevent the aircraft from taking off the deck of the carrier?What other aircraft modifications would be necessary?Does the aircraft carrier have to be modified?Is the bomber able to return to the carrier?If not, then where do they go?While traveling to the launch point with the bombers on-board, where are the bombers stored? Would the bombers fit on the aircraft carrier's elevators that are used to wheel them from the lower hanger deck to the flight deck?If the bombers are kept on the flight deck, doesn't this prevent the aircraft carrier from using its own carrier aircraft during the trip?How could this aircraft carrier protect itself and its escorts without its own carrier fighters?
Three.. bolt carrier return spring, trigger return spring, magazine release return spring.
There is no commercial air service to anywhere on the Antarctic continent. You may be able to find an air carrier that will fly you over parts of the continent and then return you to your point of departure the same day. Any aircraft that lands on Antarctica is a military, logistical aircraft bringing supplies, equipment and temporary workers and scientists to research stations supported by that government.
The aircraft carrier itself was a new technology. Although introduced during WW1 (1914-1918) it had NEVER clashed upon the high seas with another carrier fleet until May 1942 at the Battle of the Coral Sea. Then the very next month, again, at Midway. Secondly, the torpedo & dive bombers used by both forces during those carrier duels were new technology. Although torpedo & dive bombers certainly existed prior to Coral Sea and Midway...they were never used in Aircraft Carrier to Aircraft Carrier clashes before; nor were the ship borne "carrier launched" fighters, such as the Zeros and Wildcats. The Zeros and Wildcats may have tangled with each other before, but until Coral Sea and Midway, they never launched from carriers and tangled with each other. There is a BIG difference between dog-fighting with land based airplanes and dog-fighting with carrier launched airplanes. Land based planes don't have to worry about their airfield...it'll always be there! Carrier pilots had to plan on not having an airfield to land upon (to return to)...was his airfield sunk? Or lost? Or did it stray too far away? This was only one of many, of the carrier airmen's concerns.
The cost of upgrading older ships to bring them up to modern standard is estimated at about $200 million and one year in the shipyard. The cost and return was deemed inefficent in view of the current poitical climate.
If you lease something - you are temporarily using it in return for a fee. Aircraft can be leased by the hour, day, week month or more.
average return on a checking account is about 0.1
Depending on your aircraft you can use "Tiller Steering", or just use the "Rudder" for steering (NMB 0 and Return/Enter)
All of them I heard they didnt lose an aircraft!
