Richard Aboulafia and Kevin Michaels, managing directors of AeroDynamic Advisory, discuss the business aviation industry and the surprises they discovered and lessons the industry can learn as they research their book, "Time Machines: A Modern History of Business Aviation," to be published in late 2025.

Why are there only a small number of brands and not duopolies? What role did two single customers have on the industry? What can today's manufacturers learn from the past?

Hosted by Molly McMillin, editor of business aviation for the Aviation Week Network.
