“Flying from San Francisco to Los Angeles can be a huge pain in the ass. You can expect to spend over $200 on your plane ticket, plus another five hours of traveling door-to-door thanks to traffic, security, and other headaches. This is the type of hassle-rich trip — short but overly expensive and overly complicated — that a new startup called Zunum Aero is aiming to reinvent. The Kirkland, Washington-based company, which came out of stealth mode today, plans to build a fleet of hybrid electric jets to sell to major carriers for service on densely traveled regional routes like San Francisco to Los Angeles or Boston to Washington, DC. The company has received backing from Boeing and JetBlue Technology Ventures, a subsidiary of JetBlue Airways.”
