Saw the story at https: //theaviationist.com/2018/08/11/f-15cs-intercept-stolen-dash-8-airliner-out-of-seattle-tacoma-airport-before-crash/ this morning – i'm no SB, but the official story was completely bogus. Doing that kind of maneuvering in a commercial turboprop is not the kind of things a maintenance worker could pull off. Back in the day, Robert A. (Bob) Hoover would do such things in a Rockwell Commander, but keeping the load within limits is not the work of a one time crazy.
