The planned "ultra-mosque" will be a staggering 5,600ft tall - more than five times higher than the tallest building on Earth - and will be capped with an immense dome of highly-polished solid gold, carefully positioned to bounce sunlight directly toward the pavement, where it will blind pedestrians and fry small dogs. The main structure will be delimited by 600 minarets, each shaped like an upraised middle finger, and housing a powerful amplifier: when synchronised, their combined sonic might will be capable of relaying the muezzin's call to prayer at such deafening volume, it will be clearly audible in the Afghan mountains, where thousands of terrorists are poised to celebrate by running around with scarves over their faces, firing AK-47s into the sky and yelling whatever the foreign word for "victory" is.

The XF-84H was quite possibly the loudest aircraft ever built, earning the nickname "Thunderscreech" as well as the "Mighty Ear Banger".^[13] On the ground "run ups", the prototypes could reportedly be heard 25 miles (40 km) away.^[14] Unlike standard propellers that turn at subsonic speeds, the outer 24–30 inches of the blades on the XF-84H's propeller traveled faster than the speed of sound even at idle thrust, producing a continuous visible sonic boom that radiated laterally from the propellers for hundreds of yards. The shock wave was actually powerful enough to knock a man down; an unfortunate crew chief who was inside a nearby C-47 was severely incapacitated during a 30-minute ground run.^[14] Coupled with the already considerable noise from the subsonic aspect of the propeller and the dual jet turbines, the aircraft was notorious for inducing severe nausea and headaches among ground crews.^[10] In one report, a Republic engineer suffered a seizure after close range exposure to the shock waves emanating from a powered-up XF-84H.^[15]
