Fighter Combat Formations: Attacks and Escorts is a 1943 video about attacking enemy bomber formations. It stars William Forrest and Ronald Reagan, and was directed by Otho Lovering.
In World War II, escort fighters protect bomber formations from German fighters. The North American P-51 Mustang was a successful long-range escort aircraft with a range of over 1,000 miles. It was fast, agile, and had excellent maneuverability, making it ideal for escorting bombers.
