This is sometimes difficult to accomplish, when producers want sensational statements. Generally, we are satisfied with the major documentaries, which strive to be factual. Nonetheless, errors can creep in during editing, after the production crew has left the field and our direct involvement has ended. Misleading impressions are sometimes created. Then we get frantic inquiries from the mainland or elsewhere, wondering if we're about to be overrun.
Some deceptions are blatant, but they are rare.
Several years ago, a filmmaker was determined to include footage of a car imbedded in a lava flow in Kalapana but could find only rusted-out examples. We have some control over other matters. We try to tone down scientific jargon, as show biz rightfully requests, but sometimes this makes it hard to explain some of the things we do. We try to use either English or metric units, depending on the desire of the producer. This may seem simple, but the observatory, like most of the world, and all scientists, uses metric units.
