The panel itself!
He pressed one side, the other. Nothing. Ten seconds perhaps....
The bottom or the top next. But which? If it moved on a lateral axis—that would be it, for elevation or depression from the horizontal! But to accomplish what would amount to a half-loop....
He pressed the top of the panel. And it gave beneath his touch. In the viewscreen, the white mass which rushed to envelop him seemed to shift—
Further down—that was it, all the way around!
Slowly, against an unseen source of pressure, he revolved the panel a half-revolution about its lateral axis. Already he could see its reverse side—on it in the same pattern there was an identical set of control buttons, dials.
In the viewscreen there was a half-second's glimpse of the blackness of Space before the inverted ship tumbled tail-first into the white ocean of the Venus sky.
And again there was the awful sensation of falling through infinity. Desperately, he pushed the top button.
