#avgeek#aviation#airplanes#travel: Before the Boeing 747 or Airbus A380, etc., Igor Sikorsky’s 1914 16-passenger S-22 Ilya Muromets was the first airplane with 4 engines, a toilet, or food service. It also had enclosed passenger compartment, a bedroom, heating, lighting, etc.
In 1966, Charles Kao made a discovery in fiber optics: he calculated how to transmit light over long distances via optical glass fibers. Together with laser technology, his solution made telecommunication using optical fibers possible.
