Aircraft from World War Two were stunning machines, produced with a technical vision and on a scale that would have astonished engineers less than a decade before the war began.
Alas, it's now been seven decades since the war and most of those aircraft are now lost.
Fortunately at least a few are still flying, and thanks to a fantastic new advert from watch-makers Breitling we can now see them at their very best.
The clip shows a P-51 Mustang and an F4U Corsair flying above the US desert, and looking just gorgeous.
