Why do they all have to be jews??
They have to make sure they don't conduct the journey during one of their many satanic ritual holidays.
Makes sense.
They're all jews and it's roughly 3 days journey each way. They are going to have to work on the sabbath and violate their religious beliefs. Unless one or two of the kikes are atheists and will handle controls and support of the craft on it's way back to Earth.
