Answer ONE Question from each Unit All Questions Carry Equal Marks
UNIT-I
1. (a) Explain the greatest success stories in the history of aircraft technology starting from Wright
brothers. [7M]
(b) Write in detail about the development of balloons during the 18th century that flew in air and created history in lifting a human being off the ground. [7M]
