Who am I? Where are my pants?
I get why the L-39 is so popular, but I don't think anyone here can honestly say that it packs the cool factor of a true cold war fighter. I don't want to talk down to your airplane as it's faster and cooler than anything I've ever flown, but when you put it next to the legends, it really looks like a Toyota Carolla. I say that as humbly as possible, because there's nothing bad about a Carolla, it's just not as interesting [to me] as a Dodge Viper.
As has been mentioned, when you're paying the gas, maintenance, and insurance bill, "cool" is all in the eye of the beholder. An L-39 may not be a fire-breathing dragon of a fighter, but for most guys who will never fly a "real" fighter the L-39 scratches the itch.
While we're on the topic, let's just get one thing straight: nothing with a jet engine can match the cool factor of anything with a tailwheel and a radial (or V-12) up front.
