Phil Greenspun, an avid pilot, and fellow Cirrus SR20 owner, provides some commentary on what he preliminarily feels happened to the plane Yankees pitcher Cory Lidle crashed into a Manhattan condo high-rise last week. He feels that a turn at a higher rate of speed caused an aerodynamic stall, sending the plane into the building. He also comments about airspace regulations and posts a map of FAA airspace restrictions.
