I've only just seen the ad in Australia for the first time this year a few months ago but I always thought that 747's had 1 engine per pilon 2 per wing not 2 per pilon and a wing tank, I build these things as a hobby in 1/72nd scale and non of my 747's have wing tanks let alone the set-up that the ad has and besides no touareg could pull a complete 747 it must have the guts stripped out as well. Oh one more thing decommissioned civil planes don't get the interiors strip form them.
