There have been many questions asked about the recent AirAsia crash, but maybe none like this.

Fox News host Anna Kooiman recently speculated on the training of the airline's pilots, which is "similar but different" in that it uses the metric system.

"Even when we think about temperature, it’s Fahrenheit or Celsius," she said. "It’s kilometres or miles. You know, everything about their training could be similar, but different."

Hard-hitting stuff.
