Extraterrestrial craft existence 'proved beyond reasonable doubt' Pentagon chief

No evidence has been given to sustain this claim other than the usual collection of videos and photos with artifacts that can be easily explained as natural phenomena, weather balloon, foreign experimental aircraft or -more embarrassing- a bug or dirt in the camera lens.

The person making the claim has a personal interest in promoting this idea since his department budget and now his civil career after retiring depends on it.

A particular red herring on this is the tiny budget this department had. Contact with an advanced alien civilization would have incredible consequences for our society and the country leading it would secure a privileged position in the international community. Yet this department operated under a budget of 22 million dollars, basically peanuts in the military, a quarter of the price of a single F-35A.
