As federal investigators look at the scenes of two fatal plane crashes in less than week in Missouri, state transportation officials point out the safety checks they do for aviation in the state. Brian Weiler runs MoDOT’s division dealing with aviation matters. He says MoDOT does check out about 100 of Missouri’s airports. Weiler says the Transportation Department looks at safety issues at the smaller airports – trees on approaches, non-standard runway markings and lights. He says the Kirksville airport, site of this week’s fatal plane crash, sort of falls between the small, general aviation airports and the larger commercial locations. He says Kirksville gets information from both the state and federal governments.
