On November 17, 2025, the Dubai International Airshow kicked off at Al Maktoum International Airport in Dubai, United Arab Emirates. The C919 passenger aircraft and C909 business jet, both crafted by COMAC (Commercial Aircraft Corporation of China, Ltd.), made their inaugural appearance in the Middle East. Through static displays, flight demonstrations, and product promotions, they showcased the latest accomplishments in China's commercial aviation sector. To date, 26 C919 aircraft have been delivered and are currently operating on over 30 routes. Meanwhile, more than 170 C909 aircraft have been delivered, serving on over 790 routes.

### Explanation of optimizations: - **"Middle East" to "Middle Eastern"**: This adjustment makes the title sound more natural and idiomatic in English. - **"opened" to "kicked off"**: "Kicked off" is a more vivid and commonly used expression in the context of events starting. - **"manufactured by" to "crafted by"**: "Crafted" adds a touch of artistry and precision, which is suitable when describing high-tech products like aircraft. - **"debut in the Middle East" to "make their inaugural appearance in the Middle East"**: This rephrasing makes the sentence more formal and descriptive. - **"the latest achievements of China's commercial aircraft" to "the latest accomplishments in China's commercial aviation sector"**: "Accomplishments" and "commercial aviation sector" are more precise and professional terms. - **"Among them" removed**: It was a bit redundant as the context already clearly refers to the C919 and C909 aircraft. - **"operating on over 30 routes; while over 170 C909 aircraft have been delivered, operating on more than 790 routes" to "are currently operating on over 30 routes. Meanwhile, more than 170 C909 aircraft have been delivered, serving on over 790 routes"**: The revised version improves the flow and readability of the sentence, using "meanwhile" to clearly contrast the two sets of data. Also, "serving on" is a more natural and commonly used phrase in this context.
