I didn't say it was a sonic boom, I said it was a sonic boom EFFECT...
And its taken me all this time to find out where he's been hiding
I try to console myself with the thought that he didn't do it on purpose, I am sure he couldn't have seen me there struggling to return my stuff to my tent.
Our boys just don't do things like that on purpose, do they ?
But it was a very loud and very fast low level pass, I hope the practice he got was useful.
