Here is a video of a TWA 747 at max gross taking off from ATH.
Listen for the F/O call out V1 and look at the remaining runway...Do you think it would stop on the remaining runway?  :o

There are also some nice shots of the 747 and other TWA planes, along with a nostalgic look back at what was my home for forty years.  :'(
