• There you go Chris. I think the ISRO cameraman heard your lament about not being able to see the former Chairman.

  Sad not to see the usual sight of Chairman Radhakrishnan (who's left).
  

  
  Oh I think I see him in the gallery, observing!
  
  Yep, there he is!

• Is this the first time we've been able to see strap-on jettison?   I was rooting for the EDIT: Korolev Tsiolkovsky cross (but that didn't seem to materialise - it probably doesn't happen on the PSLV because of the number and the geometry of the strap-ons). Commentator said visibility was so good that we might've been able to see S1 sep, but the cameraman slewed to a shot of smoke plume. :-/
