I maybe would not say this if it was my family, but unfortunately it could happen to any of us.
How many times a day are you on auto pilot, where you pass an MSA for example and have no recollection of doing so.
It just takes a moment of lapse of concentration when the [zb] can hit the fan in various degrees of seriousness, in this case it happened to be worse case scenario.
I had something similar happen probably about 10 yrs ago. Used to do an early morning trunk from Glasgow to Dundee. This particular morning, I can remember passing Auchterarder, then nothing till I got a mile or so over the other side of the Friarton Bridge. One of the most horrible feelings I’ve ever had as I had no recollection of going up the Cairnie Brae, round the Broxden Rdbt or crossing the Friarton Br. I was obviously aware of what I was doing but I just couldn’t remember any of it. One and only time it’s ever happened thankfully.
