“Unlimited life”Of course it does not mean that you can not maintain，Does not mean that the life span can really be unlimited，But the airplane designed at that time was really strong，In our country“Snow Eagle”601Take the example of Antarctic scientific research aircraft，This aircraft is the famous World War II aircraftDC-3/C-47，Douglas Company，1944Factory，When it’s delivered to us，The life of the fuselage has been a whole70year！

“Snow Eagle”601Aircraft manufacturer、Or it’s called Basler Turbo，They passed70Years agoC-47Transport aircraft replacement avionics system、Replace piston engine with lighter weight、The more fuel-efficient turboprop engine and the replacement of some other fuselage parts were re-sold to us。
As for the price，Ok，9Digits！
This is“Unlimited life”Design concept cowXWhere：A1944Factory、The life of the fuselage has been reached70Airplane of the year，After modification, it can still meet the requirements of modern polar expeditions，You just say this idea is bullXNot cowX？!
ThisA-1“Sky Raider”The airframe of the attack aircraft also follows the same“Unlimited life”design concept，Just take good care、maintain，Don’t be beaten from the sky by the enemy，A bit ugly，Maybe Chen Geng can continue to use it for decades。
Pull a bit far，Chen Geng squinted，Look at the turboprop version with the engine installedA-1“Sky Raider”Attack aircraft，I feel quite proud，Looked for a while，He went to Brooks, who was checking the ladder from the outside and climbing down·Kanter asked：“Mr. Kanter，Can it be started？”
“Ok，”Brooks·Hom Feature nods，He and his buddies……Old friends look very excited，Thumbs up at the tester sitting in the cockpit，It means that the final inspection of the engine is completed，Everything is good，at the same time，Brooks·Kanter took the radio microphone from his assistant，To the tester：“Check completed，Engine and fuel supply are in good condition，Now the plane is handed over to you。”
Follow the normal process，The pilot has to check the system again before the plane takes off。
Even if it’s not taking off now，Just test whether the engine is working properly on the ground，But the pilots dare not care，The aircraft is inspected in detail in strict accordance with the operating procedures。
After some inspection，The tester gave a thumbs up to everyone：“Check completed，Everything is good。”
Brooks·Kanter is obviously excited，He held the intercom and took a deep breath，Loudly：“start up！”
“Yes，start up！”
Driven by a steady stream of compressed air provided by ground compressed air vehicles，PW125The engine’s turbine started to spin slowly，Then turn faster and faster，Faster and faster，When the starting speed is reached，The tester pressed the ignition button，The engine started successfully。
