Special Mugs That Break All The Time The Air Force has spent $326,785 since 2016 on a specialized coffee cup that reheat liquids aboard air refueling tankers. They cost $1,280 each, break extremely easily, and parts cannot be replaced, so it seems like some military contractor lucked into the best hustle on earth. The branch has purchased 391 of the cups in the past two year. The Air Force Rapid Sustainment Office deduced in July that replacements for the cup’s handles can in fact be 3D printed for about 50 cents, negating the need to spend $1,280 every time some clumsy pilot drops a coffee cup.
