Just as Liam Gallagher remarked that BRMC deserved their early Oasis support slots because they 'dared to look like a rock'n'roll band' so Jet see rock music with a clarity only available to those who grew up five thousand miles away in Australia.

正如Liam Gallagher评论BRMC乐队是值得他们Oasis支持的，因为他们是真正看起来象支摇滚乐队。所以Jet对于摇滚乐有着清醒的认识。在澳大利亚，他们只接受那些5000英里远来的人的采访。

The advantage of the swirling water jet breaking rock is the heavy breaking efficiency, large breaking area and less energy used to break rock per unite volume, so the swirling water jet can drill in a hole of a large diameter.

旋转射流破岩的优势在于破碎面积大、效率高、破岩比能低，因而旋转水射流能够钻出大直径的岩石孔眼。
