Smarter Every Day host Destin Sandlin recently strapped himself into a falling helicopter to prove Neil deGrasse Tyson wrong. In a tweet to comedian Chuck Nice, Dr. Tyson said that, “A helicopter whose engine fails is a brick.”
@chucknicecomic FYI: An airplane whose engine fails is a glider. A helicopter whose engine fails is a brick.

The episode also includes a video message from Dr. Tyson expressing his great interest in learning how a helicopter could land safely without an engine.
