You're right - it is a fantastic model - and a cutaway like that does work.
In my defence, I wasn't imagining anything nearly as ambitious as opening up the whole nose and roof of the fuselage to let the light in and to allow the viewer to see inside. The talk of the interior began with mention of just the bomb-bay, so I was still only thinking of that, and what I was visualising with just a hole in one side at that position wouldn't really work with the wings in the way.
When it comes to breakages, I hadn't even thought of show judges, who obviously (should - I have heard occasional horror stories) know how to treat models carefully. I always forget some modellers go in for competitions, because it's a side of our hobby that's never appealed to me.
No, I was just thinking of family and friends, and the accidents I've come home to over the years. I envy anyone who hasn't ever been met with that ashen look and the conversation along the lines of "I was only showing it to (insert name as required) and, honestly, we hardly even touched it..." as you survey the wreckage of months' of work.
All the best
