Audio Samples
The shot of a bombshell dropping by the camera in Pearl Harbor, the sfx-only track of Dinosaur (including variants) and the beginning of Madly Madagascar are good sources for sampling the first/main whistle.

The 2nd whistle can be sampled from near the end of Ice Age: Dawn of the Dinosaurs and Atlantis: The Lost Empire; it sounds similar to but should not be confused with Hollywoodedge, Sky Rocket Loud High TE021701.
