This started out from a crew who missed their hand-off coming into DTW and therefore missed their crossing restriction over Polar by a few thousand feet. Sometimes coming over the lakes our radios get kinda scratchy and fade, especially if you're IMC in precip - thankyouverymuch Bombardier. Company had to ACARS them the new freq and by the time they checked in, they just simply couldn't make the restriction... It didn't cause any conflicts, they filed a NASA report, end of story.
Some people who will remain nameless started the rumor - since I'm on the communications committee it was easy to find out it was just a rumor but when I called those who started it, they asked me to shut up about it just to see how far it would go for fun, so I actually helped perpetuate it (seemed harmless enough at the time) since I spend so much time on ready reserve in the crew rooms and EVERYONE wanted to know about it...
Unfortunately, the rumor got a bit out of hand (case in point, someone from another airline is pointing fingers without any hard facts, evidence, or firsthand knowledge and citing safety concerns), so I put the kabosh on it on our private message board and our Safety Chair substantiated the basis of the rumor as described above.
dondk is right, I've worked at a lot of places before this, and Pinnacle has developed rumor starting into an ART FORM! The problem is, there's often SOMETHING going on which is true, which makes it harder to separate fact from fiction!
