Using the Flybe web site, it's either a BAe-146, 737, or Dash-8. Using the A.net photo search engine (which is shamelessly plugged on the Flybe web site, notwithstanding its poor grammar and punctuation) and choosing Flybe as the airline and Edinburgh (EDI
) as the airport, there are 12 posted pictures of a Dash-8 and three of a BAe-146. That gives me some clue as to the probability of finding a Flybe Dash-8 and/or BAe-146 at EDI
If that's helpful at all, you hopefully now have some additional methods to research your question besides posting them here and hoping some insomniatic wingnut as myself answers them for you?
