At a large airfield surrounded by farmland in central Washington State, an electric aeroplane recently made history. It is the biggest commercial plane ever to take off and fly powered by electricity alone. For 30 minutes on 28 May, it soared above Grant County International Airport as crowds of onlookers clapped and cheered.
The biggest electric plane ever, huh? Well, it was a modified Cessna Caravan 208B – which can take a maximum of nine passengers. And the test aircraft only had a seat installed for the pilot.
