The answer was twofold. The dimmer lighting makes it easier for passengers to sleep (other passengers can always use their reading lamps). Also, in the event of a survivable crash landing (e.g. ditching, skidding off an icy runway), the passengers are not night-blind. Electrical power is lost when the engines stop (presumably no APU is running), and the transition from a brightly-lighted cabin to (near) darkness might be fatal to many passengers who otherwise would have survived. -- John Bruner (S-1 Project, Lawrence Livermore National Laboratory) MILNET: jdb@mordor [jdb@s1-c.ARPA] (415) 422-0758 UUCP: ...!ucbvax!dual!mordor!jdb ...!seismo!mordor!jdb
