Both These Warbirds Sound Great When Cutting Through The Sky
The Americans got the Mustang. The Brits got the Spitfire. Both were excellent fighter aircraft during the war and fought valiantly against the Luftwaffe. In this clip, we can compare 2 glorious sounds of 2 of the most iconic warbirds of World War II.
Over the course of World War II, a combined 35,000 Spitfires and Mustangs were built to fight for Allied air superiority
In this clip we have the Mustang up against the Spitfire. Which engine whistle sound do you prefer better? Seems like the P-51 sounds more aggressive, while the Spitfire sounds more elegant but hey, to each their own.
