Sensors on a Florida amusement park ride had been manually adjusted to double the size of the opening for restraints on two seats, resulting in a 14-year-old boy not being properly secured before he slipped out and fell to his death, according to an initial report released by outside engineers.

The average opening for restraints on the seats on the 430-foot free-fall amusement park ride located in the heart of Orlando’s tourist district was 8.3cm.
