To fly a fast jet you need a lot of thrust. The General Electric F110-GE-129 certainly provides that: At its peak output, it generates over 29,000 pounds of force.
In this image, you can see Senior Airman Daniel San Miguel overseeing a series of tests on a F110-GE-129 engine at Misawa Air Base, Japan. This image shows the afterburner phase of its operation, with the intense heat and force of the engine glowing bright against the deep black of the test chamber. The engines are tested many times at peak output before they make it into jets such as the F-16.
