Eight jet engines
The unbeatable card[1] in Top Trumps. There's no way anyone can beat the Boeing B-52 Stratocruiser, because there is not an aircraft designer in history who would be foolish enough to try to fit nine engines on a plane - these days, four is considered profligate - and unlike with the Top Trumps supercars edition there is no magnificent flying machine equipped with one wankel engine to “queer the pitch”.
