Aerospace engineering community. Professionals, graduate students, undergraduates or enthusiasts: come one, come all.
I consider "aerospace" to be a broad term encompassing all aspects of aeronautical and astronautical sciences. Refer to the aerospace engineering page from Wikipedia for elaboration. For some excellent info on the world of aerospace engineering (education advice, types of aerospace engineers, specific fields etc.), see the AIAA's "Ask An Engineer" page.
Email me, if you have questions, comments or complaints. Moderation of this community will be kept to a minimum, and I will never disable anonymous comment posting.
I, mnemonic_, am the creator of this community. Isn't it cool?
