Current AF 53rd mission will carry recon practically all the way to landfall

ALot of lightning in the eyewall once again.

Melissa wants to continue to destroy my sleep schedule...
pretty wild stuff here
If that is true that would make it the highest peak wind speed ever produced by a hurricane in the Atlantic basin, much less the highest landfalling wind speed!

Legit looks like ef2-ef3 damage over an entire town

More video from Black River. It should be noted that this location (Brigade Street) is a good quarter mile away from the coast.
I haven't seen any aftermath / damage reports from Savannah la mer east to Black River. That includes Crawford, New Hope, White House, etc. They faced the worst of Melissa. Might be awhile before we see what happened there.

No live pressure data from the recon lap in the eye wall. Awaiting sondes.

The quote in the article you linked actually said "There is no infrastructure in the region that can withstand a Category 5," which is quite a different thing than "no structure," and I would say his statement is pretty accurate. Streets, utilities, etc, can't stay totally operational when a C5 is in the picture. Basically, he's saying Jamaica did the best as they could in the face of a C5, and any country in the region would be having similar issues with their infrastructure.

All the new convection blowing up around the eye is probably preventing it from stabilizing
Are hurricane winds of this strength capable of ripping/sweeping a home off of its foundation like winds in an EF-5 tornado? Or does the updraft in a tornado also contribute to that sort of damage?

Only the storm surge can cause true EF5 style damage. Wind damage can get around EF3 levels visually but it's obviously not as simple as a comparison as you might think,
What does ATP stand for?

And the winds are measured differently too.
For hurricanes it's the highest average speed measured over a 1 minute time span in 5MPH increments with gusts measured separately. In modern times speeds must be measured on an approved anemometer or by other proven scientific method to be considered 'official'.
For tornadoes it's the highest speed reached without consideration of gusts, and usually it's estimated based on damage. I'm not sure there's an agreement on how to measure, or how long to measure these winds when measurement is possible.
Cup-type anemometers such as were all we had till modern times have a built-in 'lag' due to the inertia of the rotor and generally need about 3 seconds to stabilize to get an accurate measurement. Recent studies show that most can't be relied on for best accuracy past about 125MPH due to the behavior of wind forces on the back of the cups. I mentiion this because almost all of our record-setting hurricanes in past times were,measured this way making accurate direct comparisons with recent hurricanes impossible.
