New Delhi: Last week, US Airways Flight 1549, taking off from a New York airport, ran into a flock of birds and had to make a crash landing on the Hudson river.
Many of you may have wondered exactly the same thing I did when I read about this news: How did an Airbus A320 – a pretty big plane, moving at some speed – manage to land gently enough in a river and not sink immediately? How did it manage to stay afloat long enough for people to get out of the doors, onto the wings, and wait for boats to pick them up? What was the science behind this miracle of floatation?
Our guest this week on Just to Clarify is Dr. S.P. Govindaraju, a former faculty member in the aeronautical engineering department at the Indian Institute of Science (IISc), Bangalore. Dr. Govindaraju got his M. E. in aerospace engineering from IISc in 1964 and his Ph.D. from the California Institute of Technology in 1970. He joined IISc as an assistant professor and retired recently as a professor.
