What's the fastest you've seen a crowd go from excited to horrified?

Wow! I think I'm too late to this but I have a story:

I was a camp counselor at a sleepaway camp last summer. The most exciting event for the kids every summer is the candy drop -- a plane flies over camp and drops candy onto the soccer field. It's ridiculous.

This year, the plane flies over head and everybody ran to the soccer field! 300 kids are screaming! They're so excited! The plane flies over some trees out of sight, and then we all heard the sound a tree cracking.

The plane crashed, and thankfully the people inside were just a little scratched up. But oh boy we were horrified. I didn't know for fifteen minutes if the people in the plane were even alive. My 8-year-olds were saying we cheated them out of candy because they didn't realize what was going on and I didn't know what to say.
