We really had hoped to see the shuttle launch from Disney along with about 2 dozen other folks who had gathered just outside the Riverside Mill food court at Disney's Port Orleans Riverside resort. We had our iPad with us and watched the live streaming broadcast of the launch instead from the NASA website. The launch was running a few minutes behind schedule. Four minutes after launch, the crowd dispersed realizing we had missed it.
We've watched the shuttle launch from our backyard many, many times (about 10 miles from Disney). For daytime launches, we just get to see the contrail, but night launches provide an amazing orange glow.
I guess we'll just have to wait until the shuttle returns for the last shuttle experience - the sonic boom. We've only heard one really loud sonic boom (it woke us out of bed early one morning). It's a scary noise if you're not prepared. Whether or not we hear it depends on a variety of factors... starting with landing back in Florida!
