Rail fans call them “fallen flags.”
They are railroads that no longer exist, like the original New Haven and New York Central railroads. But before I start getting all misty eyed, let’s also pay homage to airlines that have flown away into history. There’s PEOPLExpress, the domestic discount airline that flew out of Newark’s grungy old North Terminal starting in 1981. Fares were dirt cheap, collected on-board during the flight and checked bags cost $3. You even had to pay for sodas and snacks.
