littlepuddlejumper,
The extra fuel effectively doubles the range of the 727. I don't think you will see them try to jump across the pond from Africa and fly a completely empty airplane into anything. Any 727 flying across the pond probably ends up with a fighter inspection these days anyway. More likely they would try for a high speed jump across the Mediteranean and make a stab at Buckingham Palace.
I wish they would find it too.
