question 55

Multiple Choice

In 1960 military pilot Joseph Kittinger jumped from a high altitude balloon in a fully pressurized jump suit about 100,000 feet, in the stratosphere, all the way to the ground. When in the stratosphere he felt like he was floating, even though he was free- falling in space. When he reached the troposphere he could feel the wind resistance and it no longer felt like he was floating. Why was this likely the case?

• A) It is colder in the stratosphere so the coldness numbed his ability to feel wind resistance there.
• B) The feeling was probably not real. Your senses are dulled when you reach greater heights.
• C) There is less air in the stratosphere so there was less wind resistance on his body.
• D) At higher altitudes, his brain was not receiving the oxygen it needed to process a feeling of wind resistance.
