一 6月24日13点40分。一架“空中客车”AC321型客机稳稳地停在兰州中川机场。 一高一矮,一瘦一胖,两位身着白色短袖衬衣,同样戴着眼镜的老年人随着人流依次走出机舱。 与其他旅客不同的是,他们的目光里没有惊讶和茫然,脸上也没有带出些许的兴奋与新奇。有的,只是一种老年的沉稳、成熟和强烈的使命感。 One at 13:40 on June 24. An “Airbus” AC321 passenger aircraft parked in Zhongzhou, Lanzhou, a steady airport. One high and one short, a skinny and fat, two dressed in white short-sleeved shirt, the same wearing glasses, followed by the flow of passengers out of the cabin. Unlike other travelers, their eyes were not surprised and dazed, their faces did not bring a little excitement and novelty. Some, just a calm, mature and strong sense of mission.
