Last night on ABC News, Martha Raddatz, reporting from Iraq, made clear that even if the helicopter that went down yesterday wasn't brought down by hostile fire, it still crashed because of the insurgency:

Marines often fly at night to avoid surface-to-air missiles. Twenty helicopters have gone down because of hostile fire since the beginning of the war. But there are dangers in flying at night. The pilots use night-vision goggles, which provide no depth perception, especially on desert terrain. Fog and sandstorms make the light conditions even more difficult. Pilots say it is like flying into a bowl of milk.

No, we're not winning.
