Saw this article in the Chicago Tribune — Plane piece crashes into woman's bedroom | Chicago Tribune
— and immediately thought of the number of times I've flown the landing pattern there and never once thought to pitch an empty Gatorade bottle over the side. The photo of the gear/compressor/fan thingy that fell through this woman's bedroom ceiling, landing about two feet from her bed, makes you more than a bit anxious to think of something similar happening nearby. Occasionally, aircraft bound for O'Hare fly a pattern that tracks about 1000' southeast of our house. Next time I see an MD-80 on final, I'm gonna think about it.
Live in the Chicago area? Keep in mind that aircraft approach O'Hare and Midway from almost 360° around, so there may be some valuable parts available in your backyard soon!
