"Navy investigating terrifying EA-18G Growler flight"

DN:

The temperature inside the cockpit suddenly plunged to temperatures reaching -30 degrees and a mist pumped into the the cockpit, covering the instruments and windows in a layer of ice, and rendering the pilots almost completely blind, according to several sources familiar with the incident and an internal report obtained by Defense News.

The fog inside the aircraft iced over the instrument panel, forcing the pilot and electronic warfare officer to use a Garmin watch to keep track of their heading and altitude while air controllers began relaying instructions to the crew. The pilot and EWO were forced to use the emergency oxygen supply, which was completely depleted by the end of the flight.
