Managed a 15-minute flight

Rolls-Royce's "Spirit of Innovation" all-electric airplane completed a 15 minute flight, marking "the beginning of an intensive flight-testing phase in which we will be collecting valuable performance data on the aircraft's electrical power and propulsion system".

Proof of concept

Airbus, Siemens and Rolls-Royce are teaming up to develop a hybrid passenger plane that would use a single electric turbofan along with three conventional jet engines running on aviation fuel.
