近期，美军多型军用飞机因事故停飞，致使其军用飞机出现严重缺口。 In the course of a rather sweaty and strained game, the Pittsburgh Steelers managed to defeat the Jacksonville Jaguars 16–15. However, the sport pundits note that rarely does the ultimate result of an NFL preseason game matter, as it all comes down to how well individuals and positional units execute. And the win was forced.,Trevor Lawrence, the Jaguars' second-year quarterback, directed four drives that crossed midfield as the team quickly took control. In the end, they had two successful field goals, one missed, and a turnover on downs.,Saturday's match was not a particularly run game on the offensive side of the football. On 10 carries, the Steelers' running backs gained a total of eight yards in the game. The team's No. 2 rushing back, Benny Snell Jr., gained zero yards on his three attempts. All game long, the Steelers offensive line was beaten by the Jaguars defensive front.,But it was not the game itself, which many described as disappointing, the greatest resonance among football fans was caused by the brawl that broke out in the stands - all caught on video.,Footage filmed in the stands captured a large group of agitated fans arguing loudly about an unknown disagreement. Apparently, the conflict took place between two men, one of whom has a beard, and the second is dressed in a pink T-shirt and a cap worn backwards.,Big fight at the #Jaguars-#Steelers game just now.

Within moments, everyone standing nearby is involved in a brawl.,In the video it is almost impossible to make out what the participants in the fight are saying, except for cries of profanities towards each other.,It is unknown what caused the fracas and what the size of damage to the stadium and whether anyone was badly hurt. Towards the end of the two-minute video, police officers allegedly arrived to break up the fight.,"The saddest thing about fights at public events is how no one actually knows how to throw hands, and they just flail their arms wildly in the air," one of the Twitter users said of the stadium clash. "This tweet brought to you by a fight at the Steelers jaguars preseason game.",As the club enters the halfway mark of the preseason, the Steelers are set to host the Detroit Lions next Sunday. The Jaguars will play the Atlanta Falcons next Saturday.。
二 | 8月30日，美陆军发言人宣称，由于CH-47“支奴干”直升机频繁发生发动机起火事故，美陆军已宣布停飞约400架该型直升机。据悉，发动机制造商霍尼韦尔公司在调查后声称，此次事故是由美军使用了非原厂生产的输油管O型密封圈导致燃油泄漏而引发。事实上，这已是1个多月以来美军停飞的第三款军用飞机了。8月16日，因连续发生2起坠毁事故，美空军宣布停飞所有现役52架CV-22“鱼鹰”倾转旋翼运输机。
三 | 经初步调查，事故缘于连接发动机和螺旋桨旋翼的离合器松动，导致飞机无法保持平衡最终坠毁。
四 | 7月29日，美空军宣称，因推进弹射座椅的爆炸药筒存在故障，可能影响飞行员紧急逃生，已暂时停飞全部F-35A战斗机。
五 | 分析人士认为，多型军用飞机因故障停飞给美军带来巨大压力。比如，作为美陆军的重要装备之一，此次全面停飞CH-47“支奴干”直升机将严重影响美陆军遂行作战行动的后勤保障能力。美陆军调查结果称，由于原厂配件价格昂贵且保养周期过长，美陆军不得不使用非原厂生产的O型密封圈。事实上，这体现出美军内部一贯对装备维修保养不重视、管理混乱、流程复杂等问题。
六 | 值得注意的是，美空军9月2日发表声明称，已决定全面复飞CV-22“鱼鹰”倾转旋翼运输机。
七 | 美国空军特种作战司令部公共事务负责人海斯表示，在查明事故原因前，美方将训练飞行员在理解机体特性的基础上，采取降低风险的措施，有效应对可能发生的问题。言下之意，对于CV-22“鱼鹰”运输机当前出现的问题尚无解决方案，再发生类似情况只能靠飞行员自己。
