What is which airline has the most crashes?

Based on available data, it's difficult to definitively say which airline has the most crashes overall, as metrics like "crashes per flight hour" or "crashes per passenger mile" are more relevant. However, historically, some airlines have been associated with a higher number of incidents and accidents.

• Aeroflot (formerly the Soviet Union's state airline and now Russia's flag carrier) has historically had a high number of accidents, particularly during the Soviet era. This is partially due to the sheer volume of flights it operated, less advanced safety standards, and the types of aircraft used. However, safety standards have significantly improved in recent years.

• China%20Airlines has had a number of incidents, particularly in the past.

• Other airlines with notable accident histories (though not necessarily the "most" overall) include airlines operating in regions with less developed aviation infrastructure or airlines that have since ceased operations.

It is crucial to consider that past accident records are not necessarily indicative of current safety. Aviation safety standards, technology, and pilot training have improved dramatically worldwide. Airlines that had poor safety records in the past may have implemented significant changes to improve their safety. Always refer to reputable sources of information for current safety data.
