But Jaishankar didn't move and the lady returned. Any idea what it was? High...

Re: Aerospace Engineering - Aerodynamics, Structures, Avionics, Flight Dynamics - Technical Discussions

[OT]
I seriously do not understand people bragging about getting 100 citations on a paper (and that too after 35 years). Some of my co-authors have papers (unfortunately I'm not an author on those particular papers) which gain 300 to 400 citations EVERY YEAR.

But to each their own, I guess.
