I would like to know if there exists a smooth complex projective $3$-fold $X$ that admits a fibration $\pi: X\to \mathbb CP^1$ such that all fibers are smooth, $\pi^{-1}(0)$ is the second Hirzebruch surface $F_2$ and for any $x\in \mathbb CP^1$, $x\ne 0$ the fiber $\pi^{-1}(x)$ is a smooth quadric. I suspect that in case such a three-fold exists, it will not be unique up to an isomorphism. If this is the case, can there be a classification of three-folds? Is there a "simplest one" among them?
