Thanks! That would explain a lot. I actually live in Lansdale and see planes turn here a lot...just never put 2 +2 together. As an interesting side note...while flying home from PIT back in September, I pick up our location around Pottstown (can't miss the powerplant) and noticed we were flying right towards where I live. Wouldn't you know it, we turned right over my neighborhood! I could even see my house! Not sure what out altitude was (I'm guessing 8,000-10,000 feet), but it was definitely a cool thing and wish I would have thought to get my camera out and take a picture.
