- The incident led to enhanced testing, inspection procedures, growth of in-space restore strategies, and in the end accelerated the retirement of the Area Shuttle program in 2011.
Throughout its July 26, 2005, launch, cameras captured a big piece of froth falling from house shuttle Discovery’s gasoline tank.
