Superior Safety
The MCI consisted of a rectangular cardboard carton containing one small flat can, one large can, and two small cans. It consisted of an "M"-unit can (meat-based entree item), a "B"-unit (bread item) composed of the Crackers & Candy Can and the flat Spread Can, and a "D"-unit can (dessert item). The M-1, M-3, B-1, B-2, D-2, and D-3 unit cans were small and the M-2, B-3, and D-1 unit cans were large. The ration cans were packed upright, with the flat Spread can over the large can on the left side and the two small cans were stacked one over the other on the right side (the lighter one over the heavier one). On top was the brown foil Accessory Pack and a white plastic spoon wrapped in clear plastic. Each carton contained a single complete meal providing approximately 5,000 kJ (1,200 kilocalories or 1,200 kcal), with a packaged weight of 1.2 kilograms (2.6 lb) and volume of 1.5 litres (0.053 cu ft)
Installing the unit without filters allows them to act as booster to maintain air flow in long duct legs where air flow loss due to friction is an issue
