But the area covered is not large, But the big wasp was obviously afraid of the high temperature, After seeing the salamanders coming up, they withdrew to both sides like crazy. At that time unexpectedly in the air to get out of the way of two 'gap', We were shooting and watching, In fact, I have no idea, Because the '74 spray' is used to spray so many big wasps flying around in the air, The efficiency is very low when you think about it. But that's when the miracle happened, Although the flame has a short range, For a short period of time, However, due to the sudden injection, So it still ignited dozens of big wasps, These big wasps are more flammable than gasoline when exposed to flames, Immediately turned into "small fireballs" flying in the air, However, the temperature of the '74 spray' flame was quite high. I once saw a Vietnamese soldier with a full face sprayed directly by it. It was not burned to death by the flame, but melted directly on the spot. It really melted away, leaving no ash left, leaving a scorched black mark on the place where he was sprayed.The SYN-Flood attack is currently the most common DDoS attack on the network, It is also the most classic denial of service attack. It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.After saying this passage, Zhao Mingkai's eyes looked at the light in the interview room and fell into a silence. I knew that he was thinking of sad things. He tentatively asked him how Zhou Xiaolin was doing later. He sighed deeply and said with a regretful tone:"Yes, This is 20 minutes, It is also for this reason, Alas, these 20 minutes, I felt longer than two years, Without artillery support, There have been many "halts" in the positions. So I also saw clearly what that strange smell was. How can I describe it-it looks like the strange thing like a dog before, Four feet, Round and thick body, running very fast, but the difference is its back, above is not hairless kind of skin, but one by one full of small peach size purple "blood bubble", a strange thing can carry at least more than ten, it runs, these "blood bubble" before and after the left and right trembling, that makes people see scalp pins and needles.本影片基于真实故事改编。在1986年挑战者号升空爆炸的前夕，一名工程师竭尽全力阻止飞船的发射。这位一腔热血的工程师争分多秒地争取中止这艘价值十亿美元的挑战者号飞船的发射，坚持认为O型密封环会故障失效并导致飞船全员覆灭。马歇尔太空飞行公司做出了商业层面的决策，而这位工程师做出了人性的抉择。
