In his weekly radio address President Bush said, “The opportunities America offers make our land a beacon of hope for people from every corner of the world. America’s ability to assimilate new immigrants has set us apart from other nations. In this country, our origins matter less than our dreams. What makes us Americans is our shared belief in democracy and liberty. Our Nation now faces a critical challenge: to build an immigration system that upholds these ideals and meets America’s needs in the 21st century.”

In his weekly radio address President Bush said, “This week, the thoughts and prayers of millions of Americans are with the victims of the Virginia Tech attacks. We mourn promising lives cut short.

We offered what words of comfort we could, and we were moved by the solidarity and strength of spirit we found. We wanted everyone at the university to know that this tragedy saddened our entire Nation — and that the American people stand with them in an hour of darkness.”

The aircraft that is normally used for calibrating French airport equipment was specially equipped to conduct precision approaches guided by the European Geostationary Navigation Overlay Service (EGNOS). The ATR42 plane of the Direction Générale de l’Aviation Civile (DGAC – French Civil Aviation Authority) performed a number of test approaches and landings at Limoges airport. One of the main advantages of EGNOS in this application is that it is available everywhere without the need for ground infrastructure and it provides vertical guidance for every runway. Furthermore, in the cockpit the data display is the same as for the conventional Instrument Landing System ( ILS), so there are no familiarisation problems for the pilots and no additional training costs. EGNOS, the first European satellite navigation service, launched by the European Space Agency, the European Commission and Eurocontrol, is currently in pre-operational service and will be certified for safety-of-life applications such as civil […]

ESA’s space safety interests are growing as the Agency’s own near-Earth missions increase and as space tourism and commercial flights worldwide take off.
