I would think the BAe146 and Dash 7's were only types operating in and out of LCY in 2002.
No, plenty of other types operating to LCY in 2002
Amongst others...
Dash 8 (200/300/400 series)
Saab 2000
Dornier 328
Fokker 50
ATR42
Back in 2002 I think Lufthansa were operating the route, so presumably a Bae146 / RJ
