Competition is growing in the electric Vertical Take Off and Landing market, with 407 potential builders listed in eVTOL News.  Vertical flight takes power, though, and with available batteries limiting range, most such vehicles can make only short hops.  Alternatives that allow speedier, longer flights, in the form of electric Conventional Short Take Off and Landing (eCSTOL) aircraft are in development. Such craft offer the benefit of requiring less power for takeoffs and climbs, being more aeronautically-based than power-based.  Airflow, for instance, claims operating costs for their eCTSOL craft is one-third that of an eVTOL or helicopter. We will look at three eCSTOL craft that seem to making headway at this time.  The infrastructure (in two cases below) to support …

John Langford’s New Direction

John Langford has been a leading exponent of new directions in aeronautical technology.  From his work as project manager with MIT’s human-powered Daedalus project to his executive leadership with Aurora Technologies, he has crafted electric, autonomous, and downright astonishing vehicles.   The following video is long, but insightful and exciting.   We see Langford in several early scenes. Having seen Daedalus conquer the Sea of Crete like the mythical first airman, Langford spread his reach into ever more technologically complex problems.  His resume is deceptively short, since he’s held only two jobs since leaving college.  His LinkedIn bio is brief, but telling. “John Langford is the founder and CEO of Electra.aero, a startup developing hybrid electric aircraft for regional mobility. He founded …
