SKYWALKER, WHISTLE - MORTAR WHINES

These're Skywalker Sound sound effects of a descending air whistle-like sound that perhaps debuted in Forrest Gump (1994). They kind of sound like an old-fashioned (i.e. fire truck) siren sped up in +12 pitch.

Movies

 * Bee Movie (2007) (Heard twice for the 2 raindrops that hit Barry)
 * Despicable Me (2010)
 * Forrest Gump (1994) (debut?)
 * The Peanuts Movie (2015) (Heard once when Snoopy knocks his "Sopwith Camel" off of the Eiffel Tower)

Audio Samples
Forrest Gump, of course, as well as Bee Movie and The Peanuts Movie are very good sources for these sounds. Regarding The Peanuts Movie, it should NOT be confused with "SHELL SCREAMING WHINE DOWN".
