BASE jumping

BASE jumping, also sometimes written as B.A.S.E jumping, is an activity that employs an initially packed parachute

History

The acronym "B.A.S.E." (now more commonly "BASE") was coined by filmmaker Carl Boenish
Carl Boenish
Carl Boenish considered the father of modern BASE jumping, was a freefall cinematographer, who in 1978 filmed the first jumps from El Capitan using ram-air parachutes. These jumps were repeated, not as a publicity exercise or as a movie stunt, but as a true, recurring recreational activity. This...

BASE numbers are awarded to those who have made at least one jump from each of the four categories (buildings, antennas, spans and earth). When Phil Smith and Phil Mayfield jumped together from a Houston skyscraper on 18 January 1981, they became the first to attain the exclusive BASE numbers (BASE #1 and #2, respectively), having already jumped from an antenna, spans

, and earthen objects. Jean and Carl Boenish qualified for BASE numbers 3 and 4 soon after. A separate "award" was soon enacted for Night BASE jumping when Mayfield completed each category at night, becoming Night BASE #1, with Smith qualifying a few weeks later.

During the early eighties, nearly all BASE jumps were made using standard skydiving equipment, including two parachutes (main and reserve), and deployment components. Later on, specialized equipment and techniques were developed that were designed specifically for the unique needs of BASE jumping.

However, these and other sporadic incidents were one-time experiments, not the systematic pursuit of a new form of parachuting. After 1978, the filmed jumps from El Capitan were repeated, not as a publicity exercise or as a movie stunt, but as a true recreational activity. It was this that popularised BASE jumping more widely among parachutists. Carl Boenish continued to publish films and informational magazines on BASE jumping until his death in 1984 after a BASE-jump off of the Troll Wall

. By this time, the concept had spread among skydivers worldwide, with hundreds of participants making fixed-object jumps.

Comparison with skydiving

BASE jumping grew out of skydiving. BASE jumps are generally made from much lower altitudes than skydives, and a BASE jump takes place close to the object serving as the jump platform. Because BASE jumps generally entail slower airspeeds than typical skydives (due to the limited altitude), a BASE jumper rarely achieves terminal velocity
Terminal velocity
In fluid dynamics an object is moving at its terminal velocity if its speed is constant due to the restraining force exerted by the fluid through which it is moving....

. Because higher airspeeds enable jumpers more aerodynamic control of their bodies, as well as more positive and quick parachute openings, the longer the delay, the better.

Skydivers use the air flow to stabilize their position, allowing the parachute to deploy cleanly. BASE jumpers, falling at lower speeds, have less aerodynamic control, and may tumble. The attitude of the body at the moment of jumping determines the stability of flight in the first few seconds, before sufficient airspeed has built up to enable aerodynamic stability. On low BASE jumps, parachute deployment takes place during this early phase of flight, so if a poor "launch" leads into a tumble, the jumper may not be able to correct this before the opening. If the parachute is deployed while the jumper is tumbling, there is a high risk of entanglement or malfunction. The jumper may also not be facing the right direction. Such an off-heading opening is not as problematic in skydiving, but an off-heading opening that results in object strike has caused many serious injuries and deaths in BASE jumping.

At an altitude of 600m (2,000 feet), having been in free-fall for at least 300m (1,000 feet), the jumper is falling at approximately 55 m/s (190 km/h, 120 mph), and is approximately 10.9 seconds from the ground. Most BASE jumps are made from less than 600m (2,000 feet). For example, a BASE jump from a 150m (500 foot) object is about 5.6 seconds from the ground if the jumper remains in free fall. On a BASE jump, the parachute must open at about half the airspeed of a similar skydive, and more quickly (in a shorter distance fallen). Standard skydiving parachute systems are not designed for this situation, so BASE jumpers often use specially designed harnesses and parachute containers, with extra large pilot chutes, and many jump with only one parachute, since there would be little time to utilize a reserve parachute. If modified, by removing the bag and slider, stowing the lines in a tail pocket, and fitting a large pilot chute, standard skydiving gear can be used for lower BASE jumps, but is then prone to kinds of malfunction that are rare in normal skydiving (such as "line-overs" and broken lines).

Another risk is that most BASE jumping venues have very small areas in which to land. A beginner skydiver, after parachute deployment, may have a three minute or more parachute ride to the ground. A BASE jump from 150m (500 foot) will have a parachute ride of only 10 to 15 seconds.

One way to make a parachute open very quickly is to use a static line

 or direct bag. These devices form an attachment between the parachute and the jump platform, which stretches out the parachute and suspension lines as the jumper falls, before separating and allowing the parachute to inflate. This method enables the very lowest jumps (below 60m / 200 ft) to be made, although most BASE jumpers are more motivated to make higher jumps involving free fall. This method is similar to the paratrooper

's deployment system, also called a PCA (Pilot Chute Assist).

Legal issues

The legal issues that a BASE jumper must consider concern permissions to use the object from which the jump is initiated and the area used for landing.

Surreptitious BASE jumps are often made from tall buildings and antenna towers. The general reluctance of the owners of these objects to allow their object to be used as a platform means many such BASE jumps are attempted covertly. While BASE jumping itself is generally not illegal; making events such as the "Go Fast Games" at the Royal Gorge Bridge

Jumpers who are caught can expect to be charged with trespassing, as well as having charges like breaking and entering, reckless endangerment, vandalism, or other such charges pressed against them.

The National Park Service has the authority to ban specific activities in US National Parks, and has done so for BASE jumping. The authority comes from 36 CFR 2.17(3), which prohibits, "Delivering or retrieving a person or object by parachute, helicopter, or other airborne means, except in emergencies involving public safety or serious property loss, or pursuant to the terms and conditions of a permit." Under that Regulation, BASE is not banned, but is allowable if a permit is issued by the Superintendent, which means that a mechanism to allow BASE in National Parks was always in place. However, National Park Service Management Policies have stated that BASE "is not an appropriate public use activity within national park areas ..." (2001 Management Policy 8.2.2.7.) This meant that there could be no permitted air delivery. It is noted, however, that this policy has a proposed change that strikes the language banning it outright and replacing it with a different test. Whether this will be approved, and whether this will make the granting of permits easier, is open to speculation.

In the early days of BASE jumping, the Service issued permits under which jumpers could get authorization to jump from El Capitan. This program ran for three months in 1980 and then collapsed amid allegations of abuse by unauthorised jumpers. Since then, the Service has vigorously enforced the ban, charging jumpers with "aerial delivery into a National Park". One jumper drowned in the Merced River

Upon completing a jump from all of the four object categories, a jumper may choose to apply for a "BASE number", which are awarded sequentially. BASE #1 was awarded to Phil Smith of Houston, Texas in 1981. The 1000th application for a BASE number was filed in March 2005 and BASE #1000 was awarded to Matt Moilanen of Kalamazoo, Michigan. , over 1,400 BASE numbers have been issued.
