Prospective Aero/Astro PhD

<p>What does it take to get into the top Aero/Astro PhD programs?</p>

<p>So I will be applying to the following schools for a PhD in Aero/Astro: Purdue, GTech, MIT, Stanford, UCLA, UMich? I have the following GPAs: BS: 2.85 / MS 3.54, and 5 years of work experience (NASA/Lockheed Martin). I'll be publishing a paper at an international conference and another at a national AIAA conference. I was thinking of pursing a 2nd MS since I messed up in my first 2 years of undergrad. Are there any suggestions or advice?</p>
