What Would Our Wingspan Be If We Had Wings?


The extinct bird Argentavis magnificens weighed about as much as an adult human and it had a wingspan of 7m – four times the average human arm span. This bird had lots of other adaptations to allow it to fly though, including the muscles to support these wings and flap them. Hang gliders, which allow humans to ‘fly’, are 9-10m across.


wonderful comments!

    Absolutely stunning photo. I’m not a ‘winter’ person but beautiful photos such as this I could sit in warm comfortable surroundings and look at them all day. Thank you for sharing these.

    After living in Las Vegas 35 years, it’s always a pleasure to see photos of new places being built there. This is a much appreciated picture. Thank you.
