Full of windows and usually on the edge of town, an airport terminal makes a lousy storm shelter. At Wichita Mid-Continent Airport, that should make it a high priority to plan and practice for tornado warnings. So it was alarming to learn that at least some of the 500 to 600 people at the airport during Sunday's warning were mistakenly informed that the terminal's basement was full. One of the passengers who was turned away credited security with getting people to other safe places. But before and after the new terminal opens in early 2015, Mid-Continent officials need to ensure they have the basement shelter ready and procedures in place to use it fully.
