Flight at the Edge of the Ozone Layer | One Strange Rock

thirty years ago we discovered man-made
chemicals had punched a hole in the
ozone layer is that hole here to stay
waiting around to kill us today we’re
Morgan sander is about to test an
experimental plane perfect for sampling
ozone we think we can go as high as
90,000 feet that’s the big boy territory
that’s where things can go wrong very
very quickly if we lose cabin pressure
then the pilots could very easily pass
out and we don’t have any automatic
systems to recover from that now a
glider might sound like a dangerous
choice so high up but gliders don’t have
engines which means they can’t pollute
[Music]
the purl and glider uses air rising over
the southern Andes to reach
extraordinary heights
[Music]
their speed 70 knots beautiful high
fifty-two thousand feet up makes this
the highest glider flight ever but
you’ve got to get this high to get a
great picture of the ozone layer the
good news is that thanks to a global ban
on ozone harming chemicals it looks like
the whole is healing up our our shield is regenerating
