Cruelty of Chance: The Cerritos mid-air collision and the crash of Aeroméxico flight 498

On the 31st of August 1986, a quiet holiday weekend in the Los Angeles suburb of Cerritos was shattered by a distant bang, the roar of engines, and a mighty explosion. In the skies overhead, two planes had come together in the busy airspace near Los Angeles International Airport: a private Piper PA-...

How Can a Collision Conserve Momentum, But Not Kinetic Energy?

When two objects interact in a collision, momentum is conserved where momentum (p) is defined as the product of mass (m) and velocity (v). However, if the kinetic energy also depends on mass and velocity (1/2 mv²) then shouldn’t it also be conserved? Nope. Let’s work through the who...

Badly Backed Up: The 1972 Chicago (USA) Train Collision

Chicago is a city of 2.75 Million people (as of 2020) in the north of the United States of America, located in the federal state of Illinois 135km/84mi south of Milwaukee, Wisconsin and 45km/28mi east of Naperville, Illinois (both measurements in linear distance). The location of Chicago in N...

Day Two in Europe: Collision at the Coliseum

One takes their own life in their hands by walking through town, and one eventually begins to attribute their continued breathing to a higher power. Cars and motorbikes weave between other cars wherever there is even a meter of room. One gets the impression that streetlights are more strong suggesti...

Congressionally Crushed: The 2018 Crozet (USA) Level Crossing Collision

Crozet lies on the Rivanna Subdivision, an unelectrified, partially double-tracked main line connecting Gladstone in the west with Rivanna in the east. The line is owned by Florida-based CSX Transportation, a freight train operator formed in 1980. Due to that ownership the 192km/119mi line is mostly...

Earth’s Mantle May Contain Evidence of a Planetary Collision that Formed Our Moon

Astronomers have several theories on why Earth has a moon, although one is much more widely accepted than the others. The first is known as the fission theory, which states that the Moon may be a piece of Earth that broke off during its formation due to speedy rotation. Similarly, another theory cal...

Extraordinary, moon-forming planet collision spotted 1850 light-years away

All throughout the Universe, there are normally three ways that moons can form. Pluto, shown as imaged with Hubble in a composite mosaic, along with its five moons. Charon, its largest, must be imaged with Pluto in an entirely different filter due to their brightnesses. The four smaller moons...
