The DC-9 carried 78 passengers and 4 crew. The Piper was leased to a [[Pilot certification in the United_States#Student|student pilot]] making a solo cross-country flight. The occupants of both aircraft were killed in the accident and the aircraft were destroyed by the collision and ground impact.<ref name="ntsb">[http://amelia.db.erau.edu/reports/ntsb/aar/AAR70-15.pdf NTSB Report (PDF)]</ref> == Flight history == Allegheny 853 (N988VJ), a DC-9-30, was a regularly scheduled flight departing [[Boston, Massachusetts]], for [[St. Louis, Missouri]], with stops in [[Baltimore, Maryland|Baltimore]], [[Cincinnati, Ohio|Cincinnati]] and [[Indianapolis, Indiana|Indianapolis]]. The flight departed Cincinnati at 3:15pm enroute to Indianapolis. Allegheny 853, flying under [[IFR|Instrument Flight Rules]] (IFR) clearance to Indianapolis, was instructed by Indianapolis [[Approach Control]] to descend to 2500 feet after passing the Shelbyville [[VHF omnidirectional range|VOR]] at 6000 feet. The flight was then vectored to a 280 degree heading. Meanwhile, the PA-28 (N7374J) was on a southeasterly heading operating under a filed [[VFR|Visual Flight Rules]] (VFR) flight plan which indicated a cruising altitude of 3500 feet. The PA-28 was not in communication with Air Traffic Control, was not [[Transponder#Aviation| transponder]] equipped,<ref name=tmag>[http://time-proxy.yaga.com/time/archive/preview/0,10987,901473,00.html "Death in the Skies" - ''Time'' magazine article]</ref> and there was no evidence it appeared as a primary radar target on the radarscope. == Witness reports == Eight witnesses saw the aircraft collide. They reported broken to scattered cloud cover in the area, but both aircraft were below the clouds and could be seen clearly at the time of the collision. According to the witnesses, neither aircraft attempted a collision avoidance maneuver. Wreckage analysis later concluded the PA-28's left forward side just forward of the left wing root clipped the DC-9's upper right vertical tail just below the horizontal stabilizer. == Probable cause == 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> == Passenger list == <!-----(Alphabetical order)------> {| style="background:transparent;" |- style="vertical-align:top;" | <!-----Column 1 of 3:-----> {| class="wikitable" style="line-height:1.2em; font-size:90%;" !
