Pradeep Dass gave a fascinating account of his classification, Aerospace Engineering. From some of his early inventions, which he forgot to patent, to his current brain child, a rocket engine capable of propelling (that doesn't sound right in terms of rocket engines -- does it?) a vehicle at Mach 5.
Some of our members may be able to experience flight times to Frankfurt am Main in less than an hour some time in the future. Of course you still have to check in 2 - 3 hours before departure.
Those of us born prior to the sixties will not have to worry :-)
 
Thank you Pradeep for an interesting and informative talk.
