After 180,000 km of flying and servicing this country, I sent my F-117 for medical check up. And everything is fine, even the heart has virtually no fat and colestrol. Howevera little bit of tuning is needed to make F-117 to be more quiet and leave no trace when in stealth flight mode. Hence the servicemen opened the engine and started doing some minor heart operation. Sexy gold colour -_-" no blood nothing. Only gold colour lol !!
