Shrimp Boats and Corridor-Cakes - How Airspace Got Like This

Modern pilots know airspace in terms of the alphabet system: class A, B, C, D, E, and G. Those labels are a relatively recent facade on a beast whose unnatural evolution was written in blood and bitterly contested. AGI/IGI Sal will reconstruct the National Airspace from cloud clearances in the forties to the all-weather positive control concept in the fifties to today s ADS-B requirements. Over one hundred years, personal liberty clashes with public safety and separation technology is tragically outpaced by aircraft performance. Throughout the talk, Sal will discuss online government archives that you can use to solve your own regulation mysteries. If you have an interest in history or want to know how we got to the current airspace rules, join us for this insightful presentation.
