Boeing experienced some software issues on its unmanned test of the CST-100 Starliner. One of the flaws prevented the Starliner from docking with the International Space Station. A second identified flaw could have potentially had catastrophic effect on the return from orbit. Boeing has been criticized for taking shortcuts in its software testing.
The program manager in charge of Boeing’s Starliner crew capsule program said Friday that additional checks would have uncovered problems with the spaceship’s software that plagued the craft’s first unpiloted orbital test flight in December, but he pushed back against suggestions that Boeing engineers took shortcuts during ground testing.
Mulholland said Boeing engineers performed testing of Starliner’s software in chunks, with each test focused on a specific segment of the mission. Boeing did not perform an end-to-end test of the entire software suite, and in some cases used stand-ins, or emulators, for flight computers.
Hmmm… It would seem to me that not performing an end-to-end test and using stand-ins or emulators in place of actual flight computers ARE SHORTCUTS!
I am calling BS on this one…
