While this story is actually a PR story by VW about a VQ Tuareg towing a
747, look at the photos - pay attention to the engines
http://www.autoblog.com/2006/11/22/t...di-tows-a-747/

The plane used for the stunt was a decommissioned Boeing 747-200 that weighs
155 tons. VW had initially calculated the Touareg could successfully pull
200 tons, and had even done a dry run with a 190-ton Boeing 747-400.
Unfortunately, the only plane that could be acquired for the PR stunt was
this one that is usually used as a giant prop in films.

Don't quite think this engine configuration is standard, and presumably it
isn't airworthy..
