  We study global deformations of certain projective bundles over projective
spaces. We show that any projective global deformation of a projective bundle
over $\bP^1$ carries the structure of a projective bundle over some projective
space. Furthermore, we construct examples in arbitrary dimension $\ge 3$ of
almost homogeneous Fano projective bundles over $\bP^2$ which can be globally
deformed to non-almost homogeneous manifolds.
