Yes, this is also there in the video linked by gagan (very end). This was a carefully-worded public statement prepared by ISRO for the public. But this is what happens when everything is broadcast live to public. The public knows a bit more than the official statement. We were seeing the same data that ISRO scientists were seeing in their control room. The telemetry (and therefore the communication) was clearly operative well below 2.1 km. altitude. THe public knows that the craft started to depart from the expected trajectory (the red line) at this altitude, so maybe bad things began to happen from this height downward, but telemetry was working, and is in the public domain now.Amber G. wrote:What I remember hearing from ISRO's chairman -SriKumar wrote:Clearly communication was not lost at 2.1 km.

- All things were normal till altitude of 2.1 Km
- Subsequently (some time later but they did not say when) they lost contact.
- They are analyzing the data.
(In some ways this reminds me of the very first test of the desi cryogenic engine. It ignited ...and there was applause. And the ignition did not sustain beyond a second or so...and there there was silence. This is the risk one takes in broadcasting everything live.).
