This, of course, and as many have noted here, is the BD-5, of James Bond "Octopussy" fame, for one, in which stunt pilot Corky Fornof flew THROUGH a hangar that the doors were being closed on. Someone has also posted the pertinent clip from the movie here. Not only that, he did it EIGHT TIMES, in order to get the proper shot! See:
Either the person you are talking to is misleading you, or the software they are using to track aircraft is inserting "XXXX" as a placeholder because it does not know the true callsign.
ICAO Annex 10 Volume 2 Chapter 5 discusses the standards for aviation call signs:
184.108.40.206.2 Radiotelephony call signs for aircraft
220.127.116.11.2.1.1 Full call signs
The United States Marine Corps is facing a dilemma. There are not enough combat ready fighter jets for their pilots around the world. Boeing's answer to this problem is the C+ Program. The program will take 30 retired F/A-18C Hornets and upgrade them to the most state-of-the-art platform, creating the F/A-18C+. (boeing.com, 2016, emphasis added)

Yeah, it’s the remains of an old F/A-18 classic, with its wings and tailplane removed. It also looks like they removed a substantial amount of the fuselage as well as the engines, rudders and nose radome. I’m guessing this photo was taken over NAS Jacksonville?
I believe this is a Stinson HW-75 (Also called the 105 Voyager).
I know for sure this is a Stinson aircraft due to the logo which was often rendered on the side of aircraft with a double underline and certainly has the long tail on the upper part of the S as you described:
Logo from the orignal picture, rotated and de-skewed
The identifying features which ...
That looks like the remains of a De Havilland DHC-3 Otter
It used to wear the registration VP-FAK.
British Antarctic Survey (BAS) and the de Havilland Aircraft Heritage Centre at Salisbury Hall, London Colney have agreed on a long term loan for BAS DHC-3 Otter VP-FAK. This historic artefact was recovered from Deception Island, Antarctica in April 2004 ...
As some have written in the comments, it is a Westbrook W-5-B Sportster.
Westbrook started as a company in 1929 and failed in 1931. Approximately five W-5 sportsters have been built:
[NC9N] c/n 501 destroyed in a 1931 crash
[853W] c/n 502,
[NC966V] c/n 503 lost in a 1938 accident
[NC92V] c/n 504,
possibly unlicensed one, c/n 505,

That is a Stearman-Hammond Y-S1, registration NC15524, construction number 309.
The remains of the aircraft are now owned by the Dutch aviation museum Aviodrome. They are planning to restore one of the four Stearman-Hammonds they have into flyable condition. This project is running since 2007, and is progressing very slowly.

The Space Shuttle (or "Space Transportation System (STS)") reportedly re-entered the atmosphere from low Earth orbit at about 17,500 mph, and touched down as low as 214 mph, for a ratio of 81.77.
The highest range of speeds will basically match up with a list of highest top speeds... take ~200 knots off of the top speed of the SR-71, and you probably have your answer. Or if the question is for currently flying jets, unless your #1 and #2 have top speeds so close that the delta in their landing speeds is greater than the delta in their max speeds, #1 ...
The radio-controlled model sailplane that recently exceeded 540 mph while dynamic soaring has to be a contender. Minimum speed in this flight (immediately after launch) may have been as low as 10 mph, which probably could have been sustained by staying on the front side of the ridge.

Though any plane ...
The appearance of what little of the engine is visible suggests a real airplane, not a (presumably unpowered) pretend airplane of some sort. It appears that those may possibly be the tops of air-cooled cylinders barely protruding from the side holes in the cowl.
The vertical tail looks 50's-ish or newer, w/ the squared off top. Obviously the plane had a ...
