Inconjuncts are often implicated in travel accidents and problems. Yods are two inconjuncts separated by a sextile.
Those who like playing with charts might like to look at the chart for the first manned flight - Kitty Hawk. Appleby and McCann in their book 'Eclipses' drew attention to the matches between the Kitty Hawk chart and plane crash charts.
The chart to erect is set for 10:35 a.m., Kill Devil Hill, 17th December 1903 36 02 N 75 42 W
The Kitty Hawk chart has a Yod - Saturn/MC/Neptune
The crash chart has a Yod - Saturn/MC/Chiron with Neptune 2 degrees away from Chiron
Kitty Hawk progressed to the crash date has some interesting aspects as well.
