I was flying my '48 Hikaru 1A through my living room, when I just suddenly dropped it. Luckily, even in fighter mode, the only thing that happened was that missiles were all over my floor for about an hour or so.
As for non-Macross toys, I remember the day that I bought my GI Joe Defiant, I was driving it home in my convertible and a few parts flew off of it on the freeway-luckily I was able to pull off and retrieve them...
