I think I've posted this before, but here is a real plane being towed:
OK, the un-flightworthy 747 has had its engines removed and replaced with some odd paired dummies, so it 'only' weighs 155 tonne, but the Touareg's V10 diesel actually pulls it. As well as filling the back of the car with over 4 tonne of steel, apparently VW also fitted the final drive from a V8 gas Touareg, to get more tractive effort. But a pull is a pull.
