The "science" of nature documentaries

I'm watching David Attenborough describe how birds fly. He claims that by creating high pressure under their wings they get pushed upward (fair enough) but also that the low pressure over their wings "suctions" them upward.

The idea that low pressure exerts any force on things in its vicinity was disproven over 300 years ago. High pressure pushes things. Low pressure does nothing.

Nice job setting physics back 350 years, David.


  1. Hmm, maybe relative to the pressure under their wings, but surely not relative to static pressure.
