A U.S. KC-135 refueling aircraft was lost over Iraq on Thursday, U.S. Central Command said.

Rescue efforts were underway after an incident involving two aircraft that were participating in Operation Epic Fury, the ongoing U.S. offensive against Iran.

[...]

The second plane involved was able to land safely.

A source speaking to the Associated Press on condition of anonymity said the second plane involved was also a KC-135 tanker.

[...]

The tanker is the fourth U.S. plane to go down since the war against Iran began. Last week, U.S. ally Kuwait mistakenly downed three F-15E Strike Eagle fighter jets. All six crew members aboard those jets ejected and were recovered.

Four down in two weeks seems quite a lot. 

Five crew were on the plane that went down.
