In other exciting news they are now controling planes with Linux

Engineers at IBM's Pervasive Computing Advanced Technology Laboratory created a Linux-based, intelligent, remote control system for a model airplane as a way to showcase gateway server technology. The onboard computer controls various navigational equipment and interfaces to a wireless access point and PDA. The user can control the plane through handheld wireless technology. A 3-dimensional virtual flight environment tracks the plane's flight and provides a gps-based autopilot function. The environment is based on LandSAT maps and gives the user a virtual view of the flight from the cockpit of the plane, which can be augmented by real-time updates from an onboard camera. The article briefly introduces "gateway server" concepts, describes the embedded hardware and software architecture, explains how the IBM developers implemented the control systems, and includes lots of cool photos."
