Okay. So, does that mean, the AI out of the two of us that doesn't get accepted onto the first crew can be on the second crew?

Yup
The one who dont get into the first crew will automatically become the AI for the second crew. ^^

Same with any other position that has doubles. 

I have some ideas for the seconds crew, that I will share with the captain of the second crew. So to make things work out nicely.
