NOTAM: Come with the Iran Air 747-200 or a generic A320. Your Callsign must contain Iran Air. Anyone who comes donates 1,500 tomans (15,000RLS, 0.5USD) to the Iranian Cheetah Anti-extinction program (not directly, I will give the money to the group). Don’t ask why the amount is low. It might seem to you as very little money but here in Iran it’s quite good funding.
I’d say to ask people to give it to the group directly. No offense, but people won’t trust giving their money to someone they don’t know over the Internet.
