Love that crackle sound.

Lifting approx 2,700 tons at lift-off.

Maybe not quite as loud but the crackle of a BAC One-Eleven (Speys) during take off, the Canberra bomber (Avons) and the JT8D-17 of the 737-200 and 727's, was music to the ears. And any of the original Century series US fighters with afterburners. :)
