Aerial Delivery
Illegal Aerial Delivery is a 1965 law originally set in place to prevent the resupplying of squatters in the National Parks via parachute. It has been repeatedly used against backcountry parachutists for decades.
CODE OF FEDERAL REGULATIONS, TITLE 36 - PARKS, FORESTS, AND PUBLIC PROPERTY, CHAPTER 1 - NATIONAL PARK SERVICE, DEPARTMENT OF THE INTERIOR, PART 2--RESOURCE PROTECTION, PUBLIC USE AND RECREATION
36 CFR 2.17 - Aircraft And Air Delivery
(a) The following are prohibited:
- Operating or using aircraft on lands or water [...]
- Where a water surface is designated pursuant to paragraph (a.1) of this section, operating or using aircraft under power on the water within 500 feet [...]
- 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.

8.2.2.7 BASE Jumping
BASE (Buildings, Antennae, Spans, Earth forms) jumping— also known as fixed object jumping— involves an individual wearing a parachute jumping from buildings, antennae, spans (bridges), and earth forms (cliffs). This is not an appropriate public use activity within national park areas, and is prohibited by 36 CFR 2. 17( 3)..
BASE Jumping
BASE Jumping is an acronym for the four types of fixed objects that are utilized for these foot-launched skydives: (B)uilding, (A)ntenna, (S)pan, and (E)arth. BASE jumpers first skydive hundreds of times from aircraft before attempting to BASE jump, which is undoubtedly the world's most extreme sport. Unlike skydiving, BASE jumpers typically use only one reserve parachute as the lower exit altitudes of 200-2000 feet above the ground do not normally permit deployment of a main parachute. BASE jumpers treat their single parachute as a reserve and great care is taken to insure that it works everytime.

Mesh Slider
Similar to a standard sail slider used for skydiving, a mesh slider contains a mesh material in the middle that permits air to flow through it. The increased air flow doesn't hold the slider up near the canopy as well as a sail slider during opening. Since they pose less resistance to the wind, mesh sliders come down faster and allow the canopy to open more quickly. Mesh sliders are typically used for delays from 2 seconds up to terminal velocity (with proper reefing).
Pilot Chute (PC)
A pilot chute is a miniature parachute released by a freefalling jumper in order to produce drag and subsequently pull the main or reserve parachute from the container. BASE jumping pilot chutes are typically 32"-48" in diameter and made from F-111 or zero porosity nylon with a mesh bottom. A 9' long bridle is utilized to attach a pilot chute to the main or reserve parachute. New jumpers often hold the pilot chute in their right hand for easier deployment while the more experienced prefer to store it in a spandex pocket at the bottom of the container. Contrary to popular belief, there is no ripcord or cord. Rather, jumpers typically reach for a circular disk made of thick fabric or a cylindrical plastic handle located at the apex of the pilot chute
Tailpocket
The tail pocket is a Velcro-closed pouch that holds the lines during deployment and is very similar to the pocket on most CRW canopies and reserve freebags. Parachute lines are symmetrically placed inside the tailpocket in a Figure 8 or "switchback" type pattern rather than using rubber bands as seen on skydiving rigs. Your rigger or a BASE gear manufacturer can easily sew on a tailpocket for you at cost of $20-$50.
