Re: Apollo 13 -thanks, Raoul!
The Moon was slightly further for Apollo 10 than for Apollo 13, but the A13 stack had to go further behind the Moon in order to benefit from the Moon's slingshot effect and return directly back to Earth. As a result, Apollo 13 was the furthest manned spacecraft ever:
400.171 km from Mother Earth.

After all that mission went through, I'm glad they had something positive to call their own.
Thanks, Raoul!
