the price . . .  On   the   morning   of   May   6,   1981,   the Advanced   Range   Instrumentation Aircraft, ARIA   61-0328, lifted   off   from   Wright-Patterson   Air   Force   Base   Fairborn,   Ohio.   An   hour   later   all   21   aboard perished   in   a   fatal   crash   in   a   farmers   field   while   on   a   training   mission   over   Walkersville, Maryland.   A   bronze   plaque   along   with   21   flowering   crab   apple   trees   were   placed   in   the memorial    garden    at    the    National    Museum    of    the    Air    Force    Fairborn,    Ohio,    each    tree representing a crew member or passenger. On   May   6,   1981,   EC-135N,   Serial   Number   61-0328,   call   sign   AGAR   23,   departed   Wright- Patterson   Air   Force   Base,   Ohio,   at   1005   Eastern   Daylight   Savings   Time   (EDT)   on   a   routine training   mission.   On   board   the   aircraft   were   17   crew   members   and   4   authorized   passengers. The   flight   proceeded   uneventfully   as   planned   for   approximately   45   minutes.   Then,   in   a   few brief   moments,   a   sequence   of   very   rapid   events   resulted   in   a   crash   with   the   loss   of   all   on board. At   1049:48   EDT,   the   Federal   Aviation   Administration   (FAA)   lost   radar   contact   with   AGAR   23. The   aircraft   was   cruising   at   Flight   Level   290,   at   .78   Mach   while   performing   a   navigational training leg. For   undetermined   reasons,   the   aircraft   pitch   trim   moved   to   the   full   nose-down   position.   The aircraft   then   rapidly   pitched   over,   most   likely   upon   release   of   the   auto-pilot,   and   induced sufficient   negative   "G"   forces   to   cause   the   generators   to   trip   off   line,   resulting   in   the   loss   of   all, AC   electrical   power.   The   pitch   trim   could   not   then   be   moved   electrically.   This   condition,   while unusual,   can   be   controlled   if   prompt   corrective   action   is   taken;   however,   if   corrective   action   is delayed   approximately   8   seconds,   the   aircraft   pitch   angle   will   be   greater   than   30   degrees nose-down    and    the    airspeed    in    excess    of    350    knots    indicated    airspeed.    Under    these conditions, the aircraft cannot be controlled until the pitch trim is moved toward neutral. While   it   is   evident   that   recovery   was   delayed,   the   reason   for   the   delay   is   unknown. The   aircraft became   uncontrollable   and   entered   a   steep   descent.   During   the   rapid   descent,   an   explosion occurred   at   approximately   1300   feet   above   ground   level   followed   immediately   by   catastrophic failure, and complete break-up of the aircraft.
