you are missing the point of this i am not suggesting that crashes should be implemented i am suggesting a way to make it more "realistic". i made the point that IF crashes were implemented then there would be a region in which it was expected not just at anytime
It's a rather pointless suggestion anyway. As it is, planes already cost more to operate as they age. Which is very realistic (we just need to fix the formula so the planes can remain in service for 20 years). And statistics show that newer planes crash more often than older planes, at least in the west.
Besides, it's not a question
IF crashes will be implemented. They wont be. Never. StephenM has already said no many times.
Besides, many airlines operate old planes without any problems. Delta operates DC-9s that are over 40 years old. American Airlines, SAS, Delta and Alitalia all operate antiquated MD-80s that are up to 30 years old. Southwest has plenty of 20+ 737-300s. Lufthansa operates a Ju-52, and is slated to receive a Lockheed Constellation within the next few years. Oldest mainline LH plane is a 25 year 737-300. Air Baltic has a 23 year old Fokker 50. Greenlandair operates 2 46 year old S-61s.
