Green Mesh & wrong movement

Hello,
I’m currently working on a spaceship (With Blender 2.68a & Cycles), but the Mesh of the Hull is of some reason displayed green/lime green in Wireframe mode now:




Also, i tried to animate the landing gear, bt of some reason the hull moves without keyframes:


The green mesh and the orange bar on the timeline indicates that you have set the object to be a Rigid Body. Is that really how you want to animate the object as it would explain the object falling. Remove the Rigid Body in the Physics section of the Properties window or in the Toolshelf under the ‘Rigid Body Tools’ section

Thx for the fast answer, it works fine now!
