I'm trying to find out registration of all white CRJ-100 or -200, which reg may ends ....RH. There are small titles above the first front pax windows. However I can't make them out. The second aircraft that I can't find the registration is AIRES Colombia DHC-8. It's the only AIRES aircraft there and 1 out of 3 DHC-8 stored in the southern part of the airport.
