Correct Answer
A. The Montgolfier brothers.
Explanation
the Montgolfier brothers designed the balloon, Marquis Francois d'Arlandes and Pilatre d'Rozier rode in it.
7.
Which engine does not require atmospheric air?
Correct Answer
D. Rocket
Explanation
Rockets do not require atmospheric air because they carry an oxidizer onboard the spaceship.
8.
In this picture, what does the number 27 on the runway represent?
Correct Answer
B. 270° magnetic North
Explanation
Runway headings are measured every 10° as the compass reads, so the picture represents 270° magnetic North
