The Solar Impulse, its four propellers driven by energy collected from 12,000 solar cells in its wings to charge batteries for night use, landed at John F. Kennedy Airport at 11:09 p.m. EDT, organizers said.

Intended to boost support for clean energy technologies, the project began in 2003 with a 10-year budget of $112 million.
It has involved engineers from Swiss escalator maker Schindler and research aid from Belgian chemicals group Solvay.
