Even under the cover of darkness, a solar-powered plane lifted off from Japan early Monday for the trans-Pacific leg of its flight around the world without a drop of fuel, The Associated Press reported. Swiss pilot Andre Borschberg lifted the Solar Impulse 2 at 3:03 a.m. local time from the tarmac in Nagoya, lights blazing into the predawn sky after unfavorable weather grounded it in for a month. The plane is bound for Hawaii, by far the longest — and riskiest leg of the journey yet.
