The birth of the twins
I found this Report at Episode-X.com
In the previous article, we reported that Padme's injuries, at the hand of an enraged Anakin, cause the ship she, Bail, Obi-Wan, and Yoda are on to land in order to save her babies. They land on a new world where the twins are born, and Padme finally succombs to her injuries. Today, we learn that Padme does not just die, but that she dies in the arms of a saddened Obi-Wan, much like Shmi Skywalker died in her son's arms in Attack of the Clones. LS describes it as a "really intense scene." The parallel with Episode II is interesting: just as Anakin cradles his dying mother and vows to never let such a thing happened again, so too does Obi-Wan cradle Anakin's wife, dying at her husband's hand.
My question is, how in the world is padme better of delivering the baby on a planet than on a spaceship? Why land for her to deliver her baby?
