Kerry's commanding officer, Lieutenant Commander George Elliott, stated to Douglas Brinkley in 2003 that he did not know whether to court-martial Kerry for beaching the boat without orders or give him a medal for saving the crew. Elliott recommended Kerry for the Silver Star, and Zumwalt flew into An Thoi to personally award medals to Kerry and the rest of the sailors involved in the mission. The Navy's account of Kerry's actions is presented in the original medal citation signed by Zumwalt. The engagement was documented in an after-action report, a press release written on March 1, 1969, and a historical summary dated March 17, 1969.

Sony officially unveiled PlayStation 3 (then marketed as PLAYSTATION 3) to the public on May 16, 2005, at E3 2005, along with a 'boomerang' shaped prototype design of the Sixaxis controller. A functional version of the system was not present there, nor at the Tokyo Game Show in September 2005, although demonstrations (such as Metal Gear Solid 4: Guns of the Patriots) were held at both events on software development kits and comparable personal computer hardware. Video footage based on the predicted PlayStation 3 specifications was also shown (notably a Final Fantasy VII tech demo).

Answer: Metal Gear Solid 4: Guns of the Patriots

Copper has been in use at least 10,000 years, but more than 95% of all copper ever mined and smelted has been extracted since 1900, and more than half was extracted in only the last 24 years. As with many natural resources, the total amount of copper on Earth is vast (around 1014 tons just in the top kilometer of Earth's crust, or about 5 million years' worth at the current rate of extraction). However, only a tiny fraction of these reserves is economically viable, given present-day prices and technologies. Various estimates of existing copper reserves available for mining vary from 25 years to 60 years, depending on core assumptions such as the growth rate. Recycling is a major source of copper in the modern world. Because of these and other factors, the future of copper production and supply is the subject of much debate, including the concept of peak copper, analogous to peak oil.

How much copper is estimated to exsist on earth?
Answer:
1014 tons
