A chance

I was still floating in space when Aleck called, "Vanderdecken12, are you there?"

"Yes, I read you loud and clear."

"We found a room with two machines. They appear to be used for time travel."
"That's terrific."

"Yes, but I'm not sure exactly what they do. There was a note on the door when I opened it. It said: In case I die, so that my great discoveries shall live on for the benefits of all mankind-,"

"hypocrite." I interupted.

"Although this is for all mankind, don't tell a single soul what you found. Use it only by yourself, for good, not evil. He gives the impression that he didn't want time travel to get too wide-spread."
"Yes, he also gave the impression that he was a good guy."

"Anyway, the machines appear to have instruction manuals, so I should figure them out relatively quickly. But it may still be a few more days."
