None. Apollo 11 was the first attempted (and first successful) manned lunar landing.
Apollo 11 orbited the moon 10 times before landing.
An estimated 530 million people worldwide watched the first moon landing on July 20, 1969.
The history of hot air ballooning includes several early failed attempts, particularly in the 18th century before successful flights were achieved. Notably, the Montgolfier brothers conducted multiple tests with unmanned balloons before their first successful manned flight in 1783. While exact numbers of failed attempts vary, early pioneers faced numerous challenges, including design flaws and safety concerns, leading to many trials before achieving success. Overall, the development of hot air balloons involved numerous experiments and iterations before reaching a reliable design.
It has been estimated that half a billion people watched the moon landing on TV.
It is estimated that 600 million saw the moon landing on T.V.
For every 12 feet in height, you need a landing.
