Felix Baumgartner to skydive from 23 miles up

Austrian skydiver Felix Baumgartner, 42, plans to jump from a helium balloon nearly 23 miles in the sky. If successful, he would break several world records, including highest-altitude freefall and fastest freefall and become the first human to break the speed of sound without using a machine. Baumgartner would reach speeds of more than 690mph during the 10-minute fall. His pressurized suit will be able to withstand the force of a sonic boom and temperatures of minus 70° C. Source: BBC
