It's about one-third as fast as The Space Shuttle
In other words, 5,400 knots is 0.358750 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 2.78750 times that amount.(Orbiter vehicle velocity)
The space shuttle orbits at a speed of 15,052 knots. During liftoff, the space shuttle accelerates to orbital speed in 8.5 minutes, consuming over 1.59 million kg (3.51 million lbs) of propellant in the process.
It's about three times as fast as a Bullet (Rifle)
In other words, 5,400 knots is 3.04 times the speed of a Bullet (Rifle), and the speed of a Bullet (Rifle) is 0.3290 times that amount.(5.56 x 45 mm, a.k.a. 5.56 NATO)
A 5.56 x 45 mm cartridge is fired at a velocity of 1,780 knots. As the NATO rifle cartridge, it is used by the military forces of more than thirty-one countries, including use in the M16 series, M4 Carbine, HK-416, and M249 Squad automatic weapons used by the United States armed forces.
It's about four times as fast as a Jet Fighter
In other words, 5,400 knots is 4.10 times the speed of a Jet Fighter, and the speed of a Jet Fighter is 0.240 times that amount.(for Lockheed Martin F-16, a.k.a. Fighting Falcon, a.k.a. Viper) (maximum speed at altitude)
An F-16's maximum speed at altitude is approximately 1,300 knots. The F-16 has a flight ceiling of approximately 15 km (9.32 mi).
It's about seven times as fast as a Bullet (Handgun)
In other words, 5,400 knots is 7.230 times the speed of a Bullet (Handgun), and the speed of a Bullet (Handgun) is 0.1380 times that amount.(for .40 Smith & Wesson 135 grain Sierra JHP, VV 3N37 powder, Fed. 100 primer, Remington case) (muzzle velocity)
A 0.40 caliber Smith & Wesson bullet has a muzzle a velocity of 745 knots. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990.
It's about eight times as fast as The Speed of Sound
In other words, 5,400 knots is 8.10 times the speed of The Speed of Sound, and the speed of The Speed of Sound is 0.1230 times that amount.(in dry air at 20°C)
The speed of sound in dry air at 20°C (68°F) is 667 knots. Air is a relatively poor acoustic conductor, however, as sound will travel at speeds of between 2,910 knots to 3,030 knots in water, depending on its salinity.
It's about one-fifteenth as fast as a Meteor
In other words, the speed of a Meteor is 15 times 5,400 knots.(formally Meteoroid or meteorite, depending on the context; a.k.a. "shooting star", a.k.a. "falling star")
Small meteoroids enter the Earth's atmosphere at speeds between 22,000 knots and 140,000 knots, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 5,400 knots.
It's about thirty times as fast as a Peregrine Falcon
In other words, 5,400 knots is 25.70 times the speed of a Peregrine Falcon, and the speed of a Peregrine Falcon is 0.0389 times that amount.(a.k.a. Peregrine, a.k.a. Duck Hawk, Falco peregrinus)
The Peregrine Falcon can reach speeds of up to 210 knots when diving. Falcons are sometimes sent to scare smaller birds away from airports to improve air traffic safety and were used in World War II to intercept carrier pigeons used by enemy forces.
