Problem: Break into small groups of 5-7 students. Half of the students in the group should represent the mechanic and half the students in the group should represent the bank and one student should act as a mediator. Each side should develop arguments as to why they have a greater priority in the collateral than the other assuming that the value of the plane is not enough to pay both parties in full. Each side should then present their arguments to the designated mediator who shall make a ruling.
