Jet aircraft

Epic Soundsound effect

Air line in mouth.
-Mark Estdale

Another great way to do a jet sound effect is to record a hoover – EQ to desired effect. If you have a hoover that you can adjust the power on, you can even create a sound similar to the jet powering up and powering down. Also, use a blow torch to create an after burner sound.
– Thomas Harris
