In an Aerostar flying from Venezuela to Brasil (SBBV) FL210. Just handed over to Brasil (100nm to go):
Nxxx: Boa Vista, Nxxx FL210 checking in
BV: Radar contact
Nxxxx: Boa Vista, Nxxx ready to start decent
BV: (No response)
Nxxxx: Boa Vista, Nxxx REQUEST lower for landing!
Repeated request gets no answer,
About 10nm to go
Nxxx: Boa Vista, Nxxxx, I can't seem to find any airport up here at FL210.
BV: Nxxxx, Cleared to land. Confirm gear down and locked?
Nxxx (@FL210): Cleared to land, gear down and locked (Coincidentally, the only way to get down anywhere near the Airport was idling engines and dropping the gear)
