A SU-30 Russian military fighter jet entered Estonian airspace for three minutes on Wednesday without posing a serious security threat, the Estonian foreign minister said.

The F-35 will also serve as a test bed for technologies that will become commonplace in the next generation of jets. Flying in coordination with AI-enabled drones will become a staple of any sixth-generation fighter, and those new fighter tricks will likely first arrive in the form of the F-35.
