ET Cam flashes/flares?
Looking at the launch video on the Washington Post site yesterday, the first segment from the ET Cam shows several flashes/flares near the SRB flame, with apparent bits of stuff moving out from the flashes. The time display on the WP video, which seemed to start at lift-off, had these happening between seconds 35 and 45. Any idea what those were? |

Can you post a link? There's another thread here where a possible burn
through was seen close to SRB separation. Regards, --Neurowiz |

There was condensation dripping off the orbiter before launch, as several
commentators mentioned it.

What I saw appeared to be bits of condensation on the lens moving about giving the appearance you describe. |

I did notice that while the SRBs were firing, all comms from the orbitter sounded like they were being shaken violently. Do the solids produce a rougher thrust than the liquid engines, or is this just a function of the huge weight and resonances at launche. Astronauts have often commented on how brutal, noisy and vibrating the SRBs were and how quiet the shuttle becomes once they are gone. Those who have ridden both Soyuz and Shuttle also comment on how Soyuz is much quieter than Shuttle during the first 2 minutes because of the shuttle's SRBs. For Soyuz launches, we see hwta happens when the egines are turn off, and the stuffed animal start to float. It would be nice to see the same for shuttle , with the effect in the cabin of SRB separation, and 6 minutes laters when main engines are turned off. |
