BASE takes its name from the places that the thrill-seeking jumpers often leap from: buildings, antennas, spans (bridges) and earth (usually cliff edges). (Photo by Lai Seng Sin/AP Photo)

The KL Tower International Jump sent out a global invitation for BASE jumpers to take part in this year's jump. (Photo by Lai Seng Sin/AP Photo)

There was no leap of good faith for the jumpers, who had to clearly prove their BASE credentials. (Photo by Lai Seng Sin/AP Photo)

The extreme activity has proven fatal for some over the past three decades. Since 1981 nearly 250 people are recorded to have died from the extreme activity. (Photo by Lai Seng Sin/AP Photo)

Organisers therefore stipulated that only experienced jumpers that have “consistently demonstrated good judgement with a sensible and cautious approach” should apply. (Photo by Lai Seng Sin/AP Photo)

Applicants needed to have made at least 120 BASE jumps, including 20 over the past year, to play a part in the four-day event. (Photo by Lai Seng Sin/AP Photo)

Those passed to take part were among a select group of less than 100 jumpers. (Photo by Lai Seng Sin/AP Photo)
