With shuttle launches one can see all up and down the east coast, would that be possible for Delta IV?  I am in Virginia Beach right now, so was wondering if I could briefly glance her going by if the weather is right....

I would say it's highly unlikely.  You can see the shuttle launches because their on a 51degree inclination which takes them up the east coast.  Delta IV is going to a geostationary orbit which means they'll be launch due east.

Edit: typo on the ISS inclination

The SSP hasn't flown a 57 inclination mission since STS-99 in Feb. 2000! ISS resides in a 51.6 inclination orbit.

I've never seen a launch of any kind and I happen to be in Orlando.  Will I be able to see much of anything?  Thanks.
I remember seeing a Delta launch while standing in the carport at the Orlando Airport La Quinta sometime around 1990.  I didn't know exactly what it was at the time (other than a launch), but got some details in news reports later that evening.  There wasn't much to see -- just a contrail against a clear blue sky, but I was impressed by fact that I could see it at all.

I was somewhere in L.A. late one afternoon when I saw the classic contrail of a launch from Vandenberg, probably an ICBM test flight.  That' a good distance away too.  The trail got wildly warped by winds and dissipated slowly, just like a Shuttle launch.

Back in the 60's I was living north of Atlanta and could see barium clouds from sounding rockets launched somewhere (Eglin?) on the Gulf Coast.

It gives you an impression of great height and speed, especially if you're close enough to see the exhaust flame even as a tiny bright dot.

This one should be pretty visible from Orlando since it rises vertically longer than other rockets before pitching over.  These Delta IV heavies are slow risers, max Q is under 400 psf IIRC.
If I like something on NSF, it's probably because I know it to be accurate.  Every once in a while, it's just something I agree with.  Facts generally receive the former.

When I lived in Orlando, I got to see a few STS launches from there during clear days. Pretty neat. You can follow it with your eyes until SRB separation, then it becomes a very tiny bright dot without any trail.

Unfortunately I never got to see one closer :( , since the Columbia accident occured, and I moved away before flights resumed.

There appears to be a foam patch in the fairing?  ???

The fairing is covered in insulation (not SOFI), which is painted white.  This could just be a repair spot

The orange/brown rectangular area just above the apparent repair area seems to have two regular appertures in it.  Maybe an umbilical socket for testing the payload's systems whilst it is in the fairing?

The previous Delta IVH fairing had this same "spot" on it.  I'm guessing this isn't a repair but a design feature.

There is a separation nut in that part of the fairing where the cylinder meets the nose cap

I saw the last Delta IV nightlaunch from all the way up in Jacksonville. If it's clear between Orlando and the down range, you should be able to see it. I watched the updates here on NSF and once I saw it had launched, I just walked outside and looked toward the cape. You could see it very well. I estimated the heading toward the pad and used google earth to figure the direction and then set that against local landmarks. When my Father in law came out and asked where it would be I pointed in that direction and the darned thing appeared right at the end of my finger!

I'm glued to NSF this evening.
