Solar Impulse 2 is halfway to making aviation history.The plane took off from New York's John F. Kennedy Airport on Monday and is making its way across the Atlantic Ocean to Seville, Spain. If successful, it would be the first time an emissions-free airplane has crossed the Atlantic.
Solar Impulse 2 is expected to land in Seville on June 23rd after a four-day, nonstop flight. It's not the first time the pilot, Bertrand Piccard, has made the journey, but this trip may be his most significant.&nbs
