Ian,
You've been brave and I am proud that you have expressed your responsibility.
Im sure you're off sched at the moment, but saying this Isnt to make you feel bad or to add up to the stirs around you.
This I believed is the right moment for you to reflect, to go back to the time when it happened. Where did I go wrong? What could have I done to prevent such incident? What can i share to my colleagues, so that such will not occur a second time?
There's plenty of question in your mind, Im sure. Use this time, and at the end it will not only be you who will benefit, but those around you as well.
All the best!!!
