For driverless cars, a moral dilemma: Who lives or dies?

BOSTON — What if the brakes go out in a driverless car? Does it mow down a crowd of pedestrians or swerve into a concrete wall and sacrifice its passenger?

Air Transat to test new taxiing system next year

MONTREAL — Air Transat is planning to test and deploy a new system next year that would allow an aircraft to taxi from the runway to the gate without having to use a plane’s engine, thereby cutting operating costs and greenhouse gas emissions.

The Montreal-based carrier would be the world’s first airline to use the WheelTug system, according to the company that developed it.
