Spring 1989 season
55 expeditions, of which 22 put someone on the summit. 129 summits (118 by members, 11 by hired staff) and 11 deaths, among 441 members and 19 hired staff recorded.
Summits count member records: someone who summited twice on one expedition counts once, someone on two expeditions in the season counts twice. Claimed (unrecognised) ascents are excluded and disputed ones included, as in the database's own statistics. Hired staff are only recorded when they went above base camp.
