The heaviest-ever flying bird was Argen-
tavis magnificens, which lived six million
years ago. It had a similar height and
weight to an adult human, with a wing-
span of 6m. These wings would have
been too large and hefty for continuous
flapping, so it probably flew more like a
glider, taking off by running downhill into
a headwind. We’d have to adopt a similar
flying style. - MUSCLES AND BONES
To flap these wings, we would need
pectoral muscles twice the size of a pro
bodybuilder’s. Our bones would be lighter
and therefore weaker, so we’d need to
strengthen our collarbone by fusing the
clavicles into a wishbone. We’d also need
a ‘keel’ bone protruding down the centre
of our chest, to allow the pectoral muscles
to attach further from the shoulder,
increasing their leverage. - TECHNOLOGY
Even with all of this, we probably couldn’t
fly unaided. Birds have a more efficient
one-way airflow through their lungs to get
more air with each breath, and their
muscles have extra oxygen-carrying
proteins. Their nervous system runs faster
to give them the reaction times needed for
in-flight manoeuvring. We would need help
from an oxygen cylinder, and a flight
computer with a heads-up display.
What would happen if...
humans grew wings?
