The [[NTSB|National Transportation Safety Board]] in a report adopted [[July 15]], [[1970]], released the following Probable Cause:<ref name="ntsb"/>
 
<blockquote>The Board determines the probable cause of this accident to be the deficiencies in the collision avoidance capability of the [[Air Traffic Control]] system of the [[FAA|Federal Aviation Administration]] in a [[Terminal Control Center|terminal area]] wherein there was mixed [[IFR|Instrument Flight Rules]] (IFR) and [[VFR|Visual Flight Rules]] (VFR) traffic.  The deficiencies included the inadequacy of the see-and-avoid concept under the circumstances of this case; the technical limitations of radar in detecting all aircraft; and the absence of [[Federal Aviation Regulations]] which would provide a system of adequate separation of mixed VFR and IFR traffic in terminal areas.</blockquote>
