Query: Full of information

Although the books is not a marvel or a classic piece of literature, it has a matter of fact style which gives the reader plentiful information and a welth of very well organised data regarding the Linebacker raids of 1972. John Smith writes with short, simple but powerful sentences and he also uses many first hand accounts, some of them from the Vietnamese side. I found especially useful the appendices which cover such topics as the air refuelling, the electronic war, the SEAD missions etc. The book is recommended for the serious students of the Vietnam air war, but a certain background of knowledge is necessary.
