How is it spam, don't you have to subscribe to receive Flight Safety email alerts?
They made an error and followed up to correct it. I'm cool with that.
Actually, I think it's more a case of having to unsubscribe to stop getting it. I'm pretty sure I never subscribed.
The point is though, as VH-XXX said. They didn't send out an email saying, oops, we stuffed up, here's the link, something I've seen from a lot of other organisations and companies. They just sent out another, almost identical, but corrected one, as if the first one never happened. Reminds me of something George Orwell wrote.
