Flightprep has launched an all out assault on every free planning website, and done irreparable damage to themselves in the process. They sued the owner of runwayfinder for $3.2 million. They guy is a family man that runs a free website in his spare time. Apparently they've "patented" the idea of drawing a line on a chart. They've genuinely ****ed off a majority of the GA community. I'll never buy another ASA product again, and if I see them at Sun N Fun or Oshkosh I may throw my lemonade on them after I spit in it.
