Happy Birthday Prof Lilley!

Professor Geoffrey Lilley is one of the most accomplished people I have had the pleasure of knowing. He is a legend in aeroacoustics, was instrumental in enabling Concorde to enter service, and even delved into special relativity and astrophysics. Lilley's equation is one of the most important acoustic tools for jet noise research. 11th December 2009 saw friends and colleagues reunited at Southampton to celebrate Prof Lilley's 90th Birthday. Here are some photos from this very special event.
