Editor's note: In an effort to keep the topic CCDev: Boeing Company CST-100 crew capsule focused on status updates, reader's feedback and opinions are directed to this thread.

Please use this topic to discuss the Boeing Company's development of its CST-100 spacecraft as a part of NASA's Commercial Crew Development (CCDev) program.

Here's hoping that Boeing has gotten its act together and ensures a rigorous quality control, safety and testing program for this spacecraft, unlike their 787 Dreamliner. The passenger jet has received bad press due to a recent spate of fires and inadequate testing of its batteries (the same kind of tests done on CELL PHONE batteries? Really?) I think the nation's space program — not to mention the lives of astronauts who will ride aboard CST-100- demands nothing less than excellence.

To be fair, comparing the lithium ion batteries in your cell phone to the ones used to power the 787 is a bit like comparing the tires on your car to those that were used by the space shuttle. They both include the same materials but the engineering behind them is an order of magnitude different.

In the case of the 787, it wasn't as if Boeing didn't test them, as Wired reported earlier this year:

The batteries and the airplane as a whole did undergo the most rigorous flight test certification program in airliner history. The lithium-ion batteries were approved by the FAA in 2007 after years of testing and debate over their use on the 787.
And then again, in this report describing the redesign:
Boeing's previous battery tests during original certification included crushing cells, driving nails through them and intentionally introducing short circuits to induce failure. Boeing found "nothing adverse happened" during these tests, and so it expected the battery's box and existing internal protection to be sufficient. The company says it followed the certification process set out by the FAA.
It should also be noted that Boeing has a contract with NASA to provide the same lithium-ion batteries that power the 787 for use on the International Space Station. The batteries will be installed outside the modules on an unpressurized structural hoist.

Point taken, Robert, but there are also those issues with the wiring and fires. Sloppiness at best, or serious neglect at worst. Of course, mass-producing a commercial jetliner for many customers is different from providing a spacecraft to one - but safety, above all, should be paramount in both vehicles, no? The tires on a car should not fail no more than those that were used on shuttle - the lives on board depend on it. Hopefully, Col. Chris Ferguson, STS-135 commander, will in his new role at Boeing not lose sight of that.

Have learned through some local governmental officials that a dry lake bed here in our county not to far from where I reside (the Wilcox Playa) is being seriously considered by NASA and Boeing as a recovery location for the CST-100.

Inquiries have gone out to the hospital, law enforcement and public safety agencies to determine what level of organic support can be provided and what will need to be brought in by stakeholders. 2017 was cited as when ops will commence at the Playa.
