However ,Fullerton and WIlson did not pen their obervations (having landed back at Kennedy or Heathrow airports on one of the many Air China 747s) that ferry thousands of travellers daily between China and the west.括号里里是现在分词做状语 后面是 后面是定语从句修饰 欧贝尔obervations的错了..ferry 是修饰ari china？？ china在后面that定语从句 整个句子修饰obervations 的我昨天打错了不好意思
