It’s a bird, it’s a plane! It’s actually a carton of dried blood plasma being dropped via parachute from a U.S. Navy aircraft. In 1942, the Red Cross chapter in Southeast Pennsylvania helped the U.S. military test how blood can be delivered safely from planes to military bases that were in need of blood. The plasma being dropped from the plane was placed in a waterproof package and attached to a parachute to ensure it could be easily retrieved and left undamaged from the water. ↪️ Swipe to the next photo to see if the box of plasma was recovered from the water. #RedCross #HistoricalPhotos #Navy #MilitarySupport #Pennsylvania
