I had a day like that recently, I'd gone to pick up my Samson II model from my parents house, where It had been safely in storage while we moved house. During the time I was there I decided to re-solder some of the railings that had come loose over the years and fix a chip out of the funnel and do some other general bits.
Loaded her into the boot of the car, securely in her stand, packed a couple of blankets around the sides, checked there was no movement and set off.
3 miles down the road I had to brake sharply for a cyclist who decided to suddenly veer across the road, heard a large thump and crack. Stopped to survey the damage and it turned out the glue on the stand had given way and sent the model tumbling across the boot of the car.
All the railings had been bent, the mast come off and the funnel re-chipped in an entirely new place.
I still haven't worked up the heart to repair it yet, perhaps today!
