Ahem... Thank you for taking your issues to fight club.
I was working at range comm at Point Mugu when Challenger was lost. Mugu was hooked in to 'Shuttle Net' when the launch took place, and we had direct video of the launch pad and from the cine-theodolites.
Shuttle launches had become no big thing. (Remember, NASA's motto was "Going to work in space".) So I was going to work on whatever was paying my GS-5 paycheck. Different channels of the net had the shuttle comms that everyone hears, as well as the banter between Cape radio and Canary tracking, waiting for capture. (And maybe Goddard?)
I remember the "94%", "max Q" and "go for throttle up" like everyone else, but the folks in the room grabbed my attention with "oh sh!t", "no way", and "did that just happen?" By the time I got to the monitors, things were falling into the ocean. Comms were quiet, except for the odd voice stating "lost TM". Range Safety broke in and it was done. If I remember correctly, someone had to explain the situation to Canary tracking.
We still had to revert to network news to get the story. The cameras were still focused on the launch pad and an empty piece of sky.
Godspeed to those who were lost, but it wasn't in vain. Soon after, I could go outside into a California day and hear the 'boom-boom' as the shuttle crossed over. And the last shuttle transmissions on the net before they contact Edwards Approach are always, "Thank you Barking Sands Hawaii and Point Mugu California."
