Question

The conquest of the upper atmosphere and outer space would not have been
possible without the endeavours made by adventurous balloonists. It took a great deal of courage
for the first man to step into a tiny basket and rise high into the air.
On 5 June 1783 the French papermakers Joseph-Michel Montgolfier and Jacques Etienne
Montgolfier, built a large fire over which they placed a massive balloon of linen and paper. As soon
as the air under the balloon heated up, the balloon inflated and began to rise. The people who
watched this fascinating feat were completely awestruck.
On 9 September of the same year, the brothers launched yet another hot-air
balloon. It was brightly coloured and the attached basket carried a duck, a rooster and a sheep.
The balloon rose high into the air and landed back safely. but when the balloon hit the ground, the
sheep fell on top of the rooster and broke one of its wings!
Encouraged by the success of these two trips, on 21 November, De Rozier and Marquis De
Arlandes became the first humans ever to travel in air. Their 25-minute flight covered
approximately nine kilometres and attained an altitude of 3,000 feet before landing on the
outskirts of Paris.
One of the most daring and tragic flights was undertaken in 1927 by Captain Gray,an American
flyer and scientist. On 4 November, he flew up into the atmosphere in an open gondola and a little
later the ground crew lost sight of him. As he travelled higher and higher, he kept noting down how
his body was reacting to the atmosphere. He wrote that he trembled at 10,000 feet and he was
compelled to use his oxygen mask. When he sailed 31000 feet above the sea level, the
temperature dropped to minus 32 degrees centrigrade.It was evident from his writings that his
hands trembled and his mind became foggy.As the balloon soared higher, Gray began losing
counsciousness before he breathed his last.The brave ballonist s balloon and ondola were dound
near Sparta, Tennesse. His barometer had last recorded a height of 42740 feet.​

Answer:

To obtain an accurate altitude reading in either feet or meters, the local barometric pressure must be calibrated correctly. Contents. 1 ...
