He's lying. 42 is a secret code that refers to letters of the alphabet. It's the fourth and second letter: DB
DB is a hidden operation in Germany. It's a large secret society that moves huge metal objects of unknown purpose through the country. Some people have created schedules that indicate where in the country the vessels are expected to be seen - but when you arrive on site, nothing ever happens.
At this point nobody is sure what goal DB is after, but many people assume it's to confuse and frustrate Germans to death.
I can't read German but I definitely believe it was translated. I completely missed the 42 being a reference to hitchhikers guide to the galaxy, I was hoping y'all came up with a new funny number haha.
