Not sure of that term particularly but there were reports of it happening. It was so out of the ordinarily rare and everyone wanted to get to the bottom of what the actual cause was no matter how long it took.
Now it seems to happen very frequently and no one seem to care why. Could part of it be because we are looking and searching for these stories? I'm sure that is a small part of it but a real issue that no one seems to care what the cause was and after a while the stories disappear into thin air.
Duh
