You can't compare airplanes to bike frames, there is just no way.
Aluminum or airplanes is constantly pressurized and de-pressurized,
it's not even comparable. Aluminum does have a finite life, as does
most materials. Chromoly frames are great, as long as you like heavy
bike frames, and don't go spouting off about how light the new steel
is, because at the wall thicknesses that you have to use to make a
steel frame as light as an aluminum frame, I'm thinking one crash,
and you'd be done because it would dent and or fold on you.

I've had many bikes over the years, amazingly enough, the only frame
I've ever broken was a custom steel frame. Steel is not real, step
into the 21st century my friend.
