Therefore, Bill didn't believe that this invisible plane could fly automatically.
Although he didn't believe it, Bill had no choice. The chief told him that he didn't need to operate the plane himself, so he didn't dare to act rashly.
Moreover, he didn't know how to operate an invisible plane. He could only watch the plane start and move forward by itself.
Six planes slowly left the workshop and ran to the side of the track.
Under the command of the ground crew, the invisible plane started to glide on the track.
After gliding for hundreds of meters, the plane roared and flew into the sky.
"It's really amazing!" Bill's eyes widened when he saw the ground was farther and farther away.
The invisible plane was completely beyond his imagination.
He couldn't imagine how the invisible plane flew into the sky.
This was the most advanced invisible plane in the world!
What's more, it was the most advanced fifth-generation!
