The pilots A, B, C, D, E, F, G and H are chosen as negotiators according to the following conditions:

I. A is chosen if B is chosen

II. If G is not chosen, then A and F are chosen.

IV. If F is not chosen, then G is chosen.

V. If H is not chosen, then E is chosen.

VI. If C is not chosen, then D is not chosen, and if D is not chosen, then C is not chosen.

I. A is chosen if B is chosen

II. If G is not chosen, then A and F are chosen.
