It is the small things ...

Challenger

This  is from Neil (most of them are from Melissa):

A new video has surfaced of the shuttle launch. Wow….

I barely remember it and I do not remember it getting that high before it  exploded.  

It is a haunting site.

My Wonder of the day…How important is the small stuff?  An O-ring seal was the reason for the explosion.

The Space Shuttle Challenger disaster occurred on January 28, 1986. Disintegration of the entire vehicle began after an O-ring seal in its right solid rocket booster (SRB) failed at liftoff. The O-ring failure caused a breach in the SRB joint it sealed, allowing pressurized hot gas from within the solid rocket motor to reach the outside and impinge upon the adjacent SRB attachment hardware and external fuel tank. This led to the separation of the right-hand SRBs aft attachment and the structural failure of the external tank. Aerodynamic forces promptly broke up the orbiter.

We talked about this video last night ... listen closely to the audio.

By the way, we have talked about Space, NASA, and even the Challenger on this blog before:
