This visualization from Purdue University shows how tiny invisible droplets from a single cough can flow through the cabin of a Boeing 767 passenger jet. The model is based on the assumption that the 2003 SARS virus was airborne. Airlines spent weeks touting the safety of flying and their steps against the coronavirus, passenger cabins still pose a danger for the spread of infectious diseases, experts said. It is a problem of biology, physics and pure proximity, with airflow, dirty surfaces and close contact with other travelers all at play.
