Soul, your plugs look like they are in pretty good shape externally - rusted shell is typically what snaps them off.
It's too late now, but I'm certain your problem is a combination of:
1) no thread lubrication on initial install.
2) overtorqued.
3) removing them from a hot engine. Never remove plugs out of a hot aluminum cylinder head. As the heads heat up, they expand making the spark plug hole SMALLER.
Hope you get her together o.k.
