So White Star Line could have just claimed the Titanic was a beta?
Nope. That would be like calling the iPhone 4s as a whole a Beta.
The Titanic worked for the most part. And had the crew not made some **** decisions about increasing speed etc it would have worked completely. The Titantic failure is more akin to someone jail breaking and unlocking their phone and then being made when it bricks on the new update cause they screwed with the firmware. They caused the damage by not sorting out exactly what was changing and what not to do before hand, just like the Titanic crew didn't do their research to find out the weather issues they might face so they could make appropriate course corrections, add more look out etc.
