Sorry, SDoc
Just trying to help. I recall hearing about the incident regarding the links I posted earlier. The name and altitude diff. rung a bell.
As far as DSR10's post, obviously a 747 wouldn't provide a sonic boom, but possibly wake turbulance?? Just a thought??? I worked all night, and am heading to bed. I'll check back in later tonight, hoping someone will have a definitive answer.
