UFO researcher Brad Sparks thoroughly documented a UFO heading towards Eisenhower's summer home in 1957 that was noted and documented secretly, both by Norad and Project Blue Book at the time.
They varied in altitude from 50,000 to 135,000 feet, which remains unattainable by aerospace vehicles even now, and yes, they were headed directly at President Eisenhower's summer white house.
And now we find out that Donald J. Trump, the next American president, had to skip his trip to his bed-minister New Jersey summer home because of these New Jersey drones.
