The aircraft was named ‘Flagship District of Columbia’ and was only the 12th Boeing 707 ever made. It was delivered to American Airlines in February 1959 so at the time America was taking its first steps into the void of outer space it was a mere 3 years old. It hadn’t long been out of it’s periodic inspection and with less than 8,000 hours on the airframe N7506A was expected to have a long and productive life ahead… a wish that would be dashed in a few short minutes.
