re: Challenger 604 Jet has crashed on I-75 near Naples Florida

We think of it as a way to commute to work or visit Grandma's house but the interstate system was designed and built after WW2 with a military purpose in mind. It was thought that future wars might reach our shores and we needed a logistical footprint to accommodate that. As such there were rules regarding terrain and geometry including that a certain amount has to be suitable as a makeshift runway for planes.
