In 1972, North Central Airlines Flight 575 and Delta Air Lines Flight 954
collided on a runway at O'Hare International Airport in Chicago, Illinois, in
the United States. Ten people died.
The investigation report noted that non-standard terminology – used to
expedite traffic flow – was common at O'Hare International Airport and
included the omission of words, altered phraseology, and use of
colloquialisms.
It found that the lack of clarity of wording on the part of the ground
controller and the Delta crew's failure to request confirmation that their
taxiing intentions matched those understood by the ground controller
were the major causes of the accident.
