An unusually fresh beverage was served in the air on this historic day in 1930 when a bovine named Ollie became the first cow to fly in a plane -- and the first to be milked during flight. Ollie's flight fancy soon led to a full complement of appliances such as refrigerators and ovens being moved out of the kitchen and onto aircraft. If you're moving appliances in or out, be sure you take time to protect your kitchen floor. If you fail to, a tiny sideways slip or a grain of sand caught under a wheel or slide could scratch and mar even the toughest surface. To avoid lingering reminders of moving day, at the very least create a cardboard runway before dragging heavy appliances across your floor. Better yet, create one out of 1/8-inch hardboard using shims to ride up the difference in height. Or, better yet, use new high-tech furniture glides that allow moving heavy items without damage to floors.
