When the Air Force c-141 pilots flew like that we called them frustrated fighter pilots.
Risky just for the wake turbulence off the heavy jet wing tip vortices.
I expect any turbulence edits were deleted.
fwiw the FAA requires 4 miles in trail for wake turbulence between 2 heavy jets.
couple of old turbulence videos.
