Enter a little factoid I discovered when doing some web searches on the planes (you know, because I just had to see more). Did you know the P-51 was designed and built AND airborne in 117 days. (Thanks to Wikipedia for that info.) 117 days! 117 days? Can you imagine doing that today? Think you could? Oh, and by the way, you wouldn't be able to use CAD to create your drawings. And forget about using 3D CAD models.
So that brings me to this thought. Even though today's aircraft are so much more complicated, why does it take so long to get these state of the art programs into production? Especially when so many sophisticated tools exist and are available to the engineers of today. Could it be the tools are actually complicating the process? Do the aerospace OEMs need simpler and more flexible tools?
What do you think?
