After the Kalpna Chawla Incident, How Safe Are the Astronauts and Their Spacecrafts in Space?

� Every accident has a lesson for improving the safety of space vehicles. � Spacecraft and astronauts are safer than driving in roads. � Aircraft industry though only about 50 years old, even today produces some of the most dependable man made vehicles. Can you imagine the confidence with which a pilot starts his aircraft in the morning just like starting a cycle with the same confidence and reliability. I wish such reliability levels will one day be seen in our PCs.
