WWW - Firstly, my sympathies to those bereaved after your late colleague's accident.
Whilst I'm certain that you didn't mean to taxy into a hangar and I'm sure that you probably learned about when to take control the hard way, I think that it's grossly unfair of your employer to dock your pay in such a way - are their aircraft insured?. The original tone of your other thread made it seem that you thought that the damaged strobe light didn't matter because it was already u/s. The point is that ANY 'slight' damage could conceal significant structural damage. However, if your employer starts fining people in this manner, then no-one is ever going to dare to mention any unfortunate error in the future - which is FAR more dangerous. Most of us have hides thick enough to resist some choice Anglo-Saxon (or Celtic) invective, but being hit in the pocket is simply not on!!
