Do we know if the pilots are OK? Yes, ejection can save your life, but even in a best-case scenario the forces on the human body are incredibly ugly. I know a former combat-rated RAF pilot that had to eject from a Harrier because of a low-altitude bird strike. After 6 months in the infirmary, he emerged 2cm shorter, combat rating gone forever.
Arms and legs can take a serious beating too. Airplane cockpits are pretty tight spaces, and to be explosively shot out of one with little notice is.. yikes.
