N6757Y Beech Bonanza A36TC.
2 on board (fatalities)
Aircraft flew through localiser for Rwy 05 . The controller noticed and informed the pilot. The pilot replied 'realised the mistake' and was
'Intercepting now'. That was the last transmision from the pilot. Radar
showed that the a/c speed and rate of descent increased rapidly during the next minute, until impact at 400 above msl.
The a/c struck farmland at 235kts at a 3400 fpm rate of descent. There was no fire. Both occupants suffered massive injuries.
