An airplane has two flaps that rotate upward and downward, so when an airplane tilts it's flaps downward, the wind pushes against it and causes it to liftoff.
Liftoff!!
The thrust of a rocket on liftoff can vary depending on the rocket's design and size. For example, the Falcon 9 rocket produces about 1.7 million pounds of thrust at liftoff.
The Challenger space shuttle exploded 73 seconds after liftoff on January 28, 1986.
"Everyone cheered as the operator announced "We have Liftoff" telling us the spaceship launch into the sky was successful."
A space shuttle's weight at liftoff is approximately 4.5 million pounds.
Astronauts do multiple things after the liftoff, depending on their mission. They usually take care of the flight checkup or review their mission objectives.
The first president to watch a liftoff to space firsthand was Richard Nixon. He witnessed the liftoff of Apollo 12 on November 14, 1969, at Kennedy Space Center in Florida.
A typical space shuttle weighs around 4.5 million pounds (2,041 metric tons) at liftoff.

Liftoff does not occur when a spacecraft lands; rather, it is a term used to describe the launch of a spacecraft into space. When a spacecraft lands, it typically descends from orbit or atmospheric flight to touch down safely on a surface. The operation of landing involves slowing down and controlling descent, which is the opposite of liftoff, where the spacecraft accelerates to overcome Earth's gravitational pull. Therefore, liftoff and landing are distinct phases of a spacecraft's mission.
1986
The space shuttle produced about 7.8 million pounds of thrust during liftoff.
