A rotary winged aircraft (helicopter) produced by Boeing/Vertol, it is very distinctive, having two counter rotating rotors rather than the main rotor/tail rotor setup of most helicopters. A powerful heavy-lifter, the first version introduced during 'nam could carry about six tons, the latest versions (e, f) can carry over twelve. The aircraft is designated CH-47. (CH stands for Cargo Helicopter)
The sound of a chinook is very distinctive, like some enormous jackhammer, a penetrating basso thunder that can be heard miles away, and makes the earth shake when the aircraft passes close by.
The platoon was flying into Iraq on a ch47 transport.
