Engineers have been responsible for a lot of the gear that has enabled so many people to scale Everest (or attempt it at the very least). Inevitably though, some will not survive these harsh conditions. Unfortunately, retrieving bodies from this place is not very easy to do so the majority end up staying there. As time goes on we are creating better technology but Everest will continue to consume lives.
"A good scientist is a person with original ideas. A good engineer is a
person who makes a design that works with as few original ideas as
possible" - Freeman Dyson
