So they are getting double the expected loss rate?

I don't know how you all are getting the 1-2% loss rate.

There have been five spaceworthy space shuttles (Columbia, Challenger, Discovery, Atlantis, and Endeavor) and two have been lost. That's an equipment loss rate of 40%.

I think this latest mission is the 26th mission of the space shuttle program. The two losses result in a ~4% mission loss rate.
