Great Special Effects Sounds

[Woodstock]

While watching the new Star Wars trailer, it struck me, is there a more iconic special effects sound than the Star Wars Light Sabre?

I cannot think of any specific sounds although I thought of plenty, The Predator, Alien, Darth Vader, Cylons, Star Trek Tricorder, etc., etc..

Any thoughts?

Good examples in here. Some odd ones too.

Godzilla’s roar is pretty iconic. Good memories as a kid hearing that thing go off  ;D
The Wilhelm Scream...think of westerns when cowboys and Indians scream as they get shot/impaled.

Man, I miss being a Kid in the 80’s. was a bloody fantastic  ;D
