I saw a Delta 747 in Boston last week. I didn’t know Delta flew 747s within the states. From a search, apparently, it was a military charter. Someone else had the idea of putting the takeoff on YouTube. I thought some here may be interested in watching it:

DELTA inherited the 747 from Northworst when they merged several years ago.
They (DELTA 747’s) are always flying in and out of Atlanta.
