This is well known. I'd guess that aircraft windows (esp. cockpit windows) block out more UVA that car windows though. Luckily when a young pilot is nicely roasted on one side he usually changes seats so the other side can get done too!
Anyone who spends a lot of time in harsh sunlight, particularly at altitude, is at increased risk (look at the old test pilots who spent years out at Muroc, they all look like Pancho Barnes).
Ramp rats, fuellers and handlers who are out in all weathers are equally at risk.
Moral: Wear a hat and slop on a good sun-protection cream.
