Stupid things like this do happen to us all I'm afraid. It is a great shock to see everything shattered that has taken so much time to realise into perfection. I once, when reaching over them for another model on my cupboard, pulled 10 railway wagons standing in front and coupled with my sweater 6 feet down to earth. There was also none intact anymore. They were all resin models almost finished.
I guess everybody has his own disaster stories.
The best thing might be to proceed with other projects. My main pleasure lies with the building itself and not so much with the finished result. Finding a good place for them is always a problem, with four growing up children around the house.
The finished result is mostly only appreciated by other modellers.
I see that you have already proceeded with your D.VII. I have some catching up to do
