Is there a Legendrian Neighbourhood Theorem also for noncooriented contact manifolds?
Dear @G_infinity, so, on a neighbourhood of $\mathbb P_x(T^\ast M)$ in $\mathbb P(T^\ast M)$, there doesn't exist any contact form $\alpha$, otherwise it would determine a global section of the line bundle. Thank you very much.

Dear @Petya, could you give more details about the noncoorientability of the contact structure of $\mathbb P(T^\ast M)$ in any neighbourhood of the fibers of $\mathbb P(T^\ast M)\to M$? You could also consider to post your comment as an answer.
