Let $X$ be an irreducible projective threefold, let $S$ be a ruled surface over a curve $C$, where $C$ has finitely many singular points. Let $\pi:X\rightarrow Y$ be a map such that $\pi(S)=C\subset Y$ and $\pi$ is isomorphism outside $S$. The fiber $F\cong\mathbb{P}^1$ of $\pi$ over each point $P$ on $C$ is smooth if $P$ is smooth and it is singular if $P$ is singular. $X$ is smooth outside $S$, and $\pi$ is etale outside $S$. Also I know $Y$ is irreducible three dimensional and is smooth outside $C$.
Is there a way to show that $Y$ is also projective?
