From the video description over at Liveleak.com:
For aviation history fans. Very rare color P-61 night fighter footage shot at the end of World War II. From the 422nd NFS operating out of Florennes, Belgium, an up close look at P-61 “No Nothin II.”
Then in the Pacific and the island of Saipan, the legendary 548th NFS P-61 “Bat Outta Hells.”
Including P-61 gun camera film showing a night attack with bombs, rockets and 20mm cannon.
