The BAe-146 had been the primary pure-jet to have been certified to function from London City STOLport, positioned within the docklands region, because of its steep approach capability, short-runway performance, and low noise emission. Air Wisconsin, once more launch customer for the version, had taken delivery of its first longer-fuselage BAe-146-300 on December 10, 1988, one of five which had comprised its earlier order for -200s.
