Jim Hamilton's new book is out! Falling: Amazing Survival Stories?
Jim Hamilton has written, illustrated, and self-published a new book called Falling: Amazing Survival Stories.

A Matter of Life and Death
The film A Matter of Life and Death (sometimes seen under the title Stairway to Heaven) stars David Niven as an Royal Air Force pilot who has to bail out of his plane without a parachute during World War II. He survives by some divine error. Author Diane Broadbent Friedman's book A Matter of Life and Death: The Brain Revealed by the Mind of Michael Powell (AuthorHouse, 2008) tells the story of the director of that film, Michael Powell, and how he portrayed temporal lobe epilepsy (what Niven's character was deemed to be suffering from).

Do You Want to Survive an Unplanned Freefall?
If so, check out these humorous survival tips from David Carkeet.

Two Great, But Hard-to-Find Books on the Caterpillar Club
We highly recommend both of these books, but good luck finding them, they are difficult to come by:

Here's another book on the Caterpillar Club, though there's not much in it on falling it does include a great list of the early Caterpillar Club members:
Two Intriguing Long-Fall Survival References
They Fell Without Parachutes - And Lived!
Paul Brickhill, the author of The Great Escape wrote an article called They Fell Without Parachutes - And Lived! It appeared in the June 1950 issue of Blue Book magazine. Many thanks to William Contento and Mike Ashley for their help in locating this article for me. Brickhill was in prison camp with many aviators and spoke to Nicholas Alkemade, Joe Herman, and others about their experiences and recorded them in this article. This is likely the first published account of such stories. In regard to the Free Fall Research Page it is like the Rosetta Stone.

Note: It turns out that Brickhill covered this content earlier with the 1946 publication (with Conrad Norton) of the book, Escape to Danger.

Another note: Brickhill fans would do well to check out Stephen Dando-Collins' 2016 biography, The Hero Maker: A Biography of Paul Brickhill. In addition to "The Great Escape," other hero-making works by Brickhill include The Dambusters and Reach for the Sky: The Story of Douglas Bader.

Human Survivability of Extreme Impacts in Free-Fall
For those of you who are interested in a scientific take on surviving falls from around 50 to 250 feet, you should look into the work of Richard G. Snyder. In the 1960s Snyder was the author or co-author of two interesting pieces of research: Neither of these documents describes falls out of airplanes (there is a lot on suicidal jumps from the Golden Gate Bridge however), but they do have a connection to airplane accidents, as becomes clear from Mary Roach's book Stiff: The Curious Lives of Human Cadavers. Roach describes Snyder's work because of its value in determining the cause of an airline disaster over deep water, where the only evidence that may be available are the recovered bodies of passengers.

Both of these articles are available from NTIS, the National Technical Information Service. If you are interested in purchasing either of these documents, NTIS can be reached at 800-553-6847 or
www.ntis.gov.

Update: One of Dr. Snyder's studies is available in its entirely on the web. See Study of Impact Tolerance through Free-Fall Investigations (1977).

Hugh de Haven and Richard Snyder
IP Online, an international peer review journal for health professionals and others in injury prevention, has in its web-accessible database a 1942 study by Hugh de Haven called Mechanical analysis of survival in falls from heights of fifty to one hundred and fifty feet. These folks didn't fall out of airplanes, in fact, it appears as if most jumped from apartment buildings. The writing is clinical and the subject is pretty gruesome, but de Haven's work takes the details from these sad tales of survival with the intent of using the knowledge gained to improve the survival chances of people in aircraft and automobile accidents.

De Haven's work was continued by Richard Snyder (see above) whose research entitled Human Survivability of Extreme Impacts in Free-Fall and Fatal Injuries Resulting from Extreme Water Impact are part of the body of research that helped in the development of seatbelts and airbags. Snyder's work first came to our attention in Mary Roach's book Stiff: The Curious Lives of Human Cadavers. Roach describes Snyder's work because of its value in determining the cause of an airline disaster over deep water, where the only evidence that may be available are the recovered bodies of passengers. Their injuries may provide clues about the cause of the accident.

The de Haven study is overwhelming reading. When you are done reading you want to go outside and take a breath of air. It's not the kind of life's work that a typical person could face day-in/day-out. IP Online calls Mechanical analysis... an "Injury Classic." If you are interested in having a look, check out IP Online and search on "de Haven" to find de Haven's study.

Note: Tim Hoult wrote in to say "De Haven's work is incredibly important in the field of crash protection - it seemed to kickstart the industry into actually doing something. Even more amazing is the fact that he might not have been around to write it. He was the only survivor in a mid-air collision of two JN-4s several hundred feet above the ground in 1917 - his major internal injuries only being caused by, ironically, his seat belt buckle!"

The Experience of Falling
Who knew that there was research on the experience of falling? One of the earliest must have been Albert van St. Gallen Heim's 1892 treatise on The Experience of Dying from Falls, which was translated into English quite some time later by a pair of researchers named Russell Noyes, Jr. and Roy Kletti. Noyes and Kletti wrote a number of scientific articles including: Survivors, many of them fallers, experienced a feeling of detachment from their bodies, an altered perception of time, and a sense of depersonalization. There appears to be a whole science (or pseudoscience) of near-death experiences (known to the field as NDEs). Thanks to John Thackray for telling us about the work of Noyes and Kletti!

I guess if you survive a fall with a failed parachute, you feel like writing a book: Other Books that Reference Long-Fall Survival
Poetry Corner
At least two important poems are based on stories of people who fell to their deaths from airplanes: Novels about Falling
Falling themes are fairly common in novels:
