What's up with all these threads asking about the 'best' schools...
Best is subjective. I can tell you that UT Austin and Texas A&M have rigorous AE programs that are comparatively easy to get into as an international student. I say comparatively because they're by no means easy to get into, but it's much easier to get into a school like UT and A&M than into, say, MIT. Whether they're the 'best' or not is entirely up to you.
Also, just as a side note, don't you think it's a little presumptuous that you could even get into the 'best' aerospace engineering school? Just saying...
