Hartwig Baier, a well known international aircraft broker for many decades, died suddenly last week at the age of 73 while vacationing in the Bahamas. He began his business aviation career as an engineer with Lear Jet, before migrating to Cessna’s newly established Citation program and later Canadair’s (now Bombardier’s) Challenger program. In 1986 he formed his own company: International Aviation Consultants.
