Editing BASE jumping (section)

=== BASE numbers ===
BASE numbers are awarded to those who have made at least one jump from each of the four categories (buildings, antennae, 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, [[span (engineering)|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.

Upon completing a jump from all of the four object categories, a jumper may choose to apply for a "BASE number", awarded sequentially.<ref name="numbers">{{cite web|url=http://www.basenumbers.org/ |title=Base Numbers |publisher=Base Numbers |access-date=2010-05-18| archive-url= https://web.archive.org/web/20100511195457/http://www.basenumbers.org/| archive-date= 11 May 2010 | url-status= live}}</ref> The 1000th application for a BASE number was filed in March 2005 and BASE #1000 was awarded to Matt "Harley" Moilanen of Grand Rapids, Michigan. {{As of|2017|05}}, over 2,000 BASE numbers have been issued.<ref>{{cite web|url=http://www.basenumbers.org/ |title=BASENumbers.org |publisher=BASENumbers.org |access-date=2017-05-19}}</ref>
