Airbus has been running some ads lately, notably one in The Wall Street
Journal, _strongly, strongly implying_ that four-engine airliners are
safer than two-engine craft.  "When you're flying over water in remote
locations... you really want to be between four engines," or words to
that effect.  Very interesting.  First time I can remember an aircraft
company making a competitive safety claim in an advertisement.  I wonder
if they have any statistics to back it up?
