• February 2, 2007 - An Apache helicopter was shot down near Taji killing two crew members.

The names of these two crew members have not yet been released pending notification of next of kin.

Since May of 2003 the U.S. has lost approximately 50 helicopters, 50% due to hostile fire. 

Four helicopters shot down within a two-week period of time, all due to hostile fire is a significant loss, especially when the Islamic State of Iraq, a group linked to al-Qaida, claimed responsibility for the February 2 crash.  The following statement published by the Chicago Tribune indicates the insurgents may have developed new methods of threatening U.S. air missions.

"The air-defense brigade of the Islamic State of Iraq successfully shot down an Apache helicopter and burnt it completely near the oil reservoirs in Taji, Albu Assaf area," the statement said, promising to post pictures of the attack soon.

"Allah has helped its soldiers and showed them new methods for confronting your air force."

Are they just lucky shots or does the insurgency actually have new methods for shooting down our helicopters?  The military has confirmed that all four helicopters were brought down by hostile fire. 

Four helicopters and 21 lives lost in two weeks - how many more losses can the U.S. afford?
