Passenger Takes Over Intercom On Plane With A Memorable Announcement

What a fun video.  However, if I was on this plane and suddenly a passenger stood up, walked over to the in flight intercom and said he had a message and there were some things he wanted to say, I might have started feeling a bit uneasy.  There would have been no need to feel those feelings though.  After he spoken those words, explained his story, the plane's passengers suddenly erupted in applause.  Nice to see that Delta went along with the little surprise!  But, isn't there some kind of law against passengers speaking on the plane's intercom????
