Meteors attack! Six tales of impacts from above

Whether you're a skywatcher or not, when space rocks roar through our atmosphere, it's hard not to notice, and this past week was an active one.

There was that fireball that streaked across the sky over southern Ontario, that brought to mind the meteor that exploded over Russia last year. 

But while the Russian rock caused some damage when it blew, it would have been catastrophic if it had actually hit the Earth.

Which, ah, happens a bit more often than people might like. Below are just six space rocks that impacted our planet's surface, with effects ranging from reverence, to extinction.

The Carancas Impact, Peru

The people of the small Peruvian village of Carancas, near the border with Bolivia, must have thought they were under attack when this meteor streaked down from the sky and smashed into the area, leaving a 15-metre-wide crater.

The shockwave shattered windows, and debris was flung 250 m, damaging the roof of at least one building. You can glimpse the crater and damage in the first couple of minutes of this Latin American news report:

It must have seemed even worse when groundwater rushed into the six-metre-deep crater, began to boil, and emitted a noxious odour that made around 30 people ill.

Fortunately, it turned out it wasn’t a biological or chemical weapon attack. The meteorite blasted deep enough to reach an underground water deposit contaminated with natural arsenic, which evaporated into fumes laced with the stuff. The people who fell sick after approaching the crater were fine after a few days, and the force of the blast “only” came to the equivalent of four tonnes of TNT.

But it made scientists sit up and take notice, and not just for the explosion. The meteorite was mostly made up of rocky materials, and the conventional wisdom was that meteors of that kind under 100 m in size aren't large enough to survive intact all the way to the Earth’s surface. This one slammed into the ground at 24,000 km/h.

The new theory is that, rather than disintegrating and raining rock fragments over a wide area, the conditions were just right for the pieces of this meteor to stay together, and possibly even form a different, more aerodynamic shape on the way down.

If rocks that small (it was believed to have been around 1 m wide) can make it through our protective atmosphere, the risk and frequency of that happening may be higher than we thought…

Peekskill meteorite, New York

There are tons of videos of the Peekskill meteorite on YouTube, a major milestone in itself, given that its fiery passage through the sky was captured on film in the ancient days of 1992.

And we mean “on film” literally. The rock happened to make its appearance around high school football time, so no less than 16 recordings exist, submitted by amateur videographers at nighttime games from Ohio to South Carolina and New York.

You can clearly see the green-tinged fireball breaking into smaller chunks in some shots, but the parent rock is believed to have been up to a metre in diameter.

New York State, incidentally, was the most famous last stop of one of those fragments. At top speed, it was going at an estimated 52,000 km/h, but air friction drastically reduced that velocity by the time it made landfall near the home of the Knapp family.

Problem: Between it, and the ground, was the trunk of Michelle Knapp’s 1980 Chevrolet Malibu.

She found the fragment in a small impact crater beneath the car, but the vehicle itself was the real star from then on, and no wonder!

Knapp made a killing by selling the car, which she’d bought for $400, to the wife of a meteorite collector for a big mark-up of $10,000.

That collector, Allan Langheinrich, toured the car around museums across the United States, Europe and Japan, in the same condition it was when he first acquired it, dented trunk and all.

At last report, the world-famous “meteorite car” is part of the Macovich collection. Out of curiosity, we’d love to see the insurance bill if they ever try get it roadworthy again. 

Hodges meteorite, Alabama

Ann Hodges was feeling a little under the weather when she decided to take a nap on her couch one day in Alabama’s Talladega County in 1954. But her plan to catch 40 winks was mercilessly crushed when a small meteorite smashed through her ceiling, grazing her hip and damaging her radio.

She didn’t now it then, but that meteorite would all but ruin her life.

After a geologist confirmed it was a meteorite, it was turned over to police, who passed it on to Air Force intelligence services. Once they’d confirmed its otherworldly status, they sent it to the Smithsonian. Who then refused to return it to Alabama, until a congressman intervened.

Then the real nightmare started for Hodges. The owner of the home she and her husband were renting, mindful of the repair bill, sued her for possession of the meteorite. The case went back and forth through the courts before Hodges ended up buying the very rock that smacked into her hip for the then-princely sum of $500.

And while all of this was going on, a massive media frenzy engulfed the Hodges, causing even more stress. Apparently unskilled in bargaining, they held out on selling the rock for the highest price for so long, interest ebbed away.

They ended up just donating it to a museum, but the ordeal had taken its toll. Both Ann and her husband cited the meteorite experience as a factor in ending their marriage when they divorced in the 1960s. She herself died of liver failure in 1972.

Incidentally, meteor showers seem to be part of Alabama’s heritage. One such, in 1833, entered state lore to the point where it inspired the jazz number “Stars over Alabama,” eventually covered by Frank Sinatra.

The first recording was in 1934, ten years before Hodges’ fateful encounter.
