The Ground Effect Objection Debunked
I'm not sure if we've linked to this article (link fixed, sorry) before, but I didn't find any mention of the term "ground effect" on the blog. The article goes into great detail on what ground effect is and why it doesn't matter.
One of the pilots summarized his experiences by stating, "This whole ground effect argument is ridiculous. People need to realize that crashing a plane into a building as massive as the Pentagon is remarkably easy and takes no skill at all. Landing one on a runway safely even under the best conditions? Now that's the hard part!" While he may have been exaggerating a bit for effect, he does raise a valid point that flying skillfully and safely is much more difficult than flying as recklessly as the terrorists did on September 11.
