Changing our weather one flight at a time

DiscoveryNews has an interesting article on the subject of commercial airliners minutely changing weather patterns.  In some cases snow and rain was caused by flying through clouds in certain types of conditions.  The hole punch clouds that can occur when this happens are even cited as "evidence" of UFO landings.

The part I thought was the most interesting was this excerpt:

"Still, Heymsfield and colleagues write in a new study in Bulletin of the American Meteorological Society that on average, 7.8 percent of Earth is covered in clouds ripe for "plane seeding." Heymsfield notes that precipitation from this effect isn't likely to alter global weather patterns, it may have a local effect."
