Conversation overheard on the VHF Guard (emergency) frequency 121.5 MHz while flying from Europe to Dubai . It's too good not to pass along.. The conversation went like this... Iranian Air Defense Radar: 'Unknown aircraft you are in Iranian airspace. Identify yourself.' Aircraft: 'This is a United States aircraft. I am in Iraqi airspace.' Air Defense Radar: 'You are in Iranian airspace. If you do not depart our airspace we will launch interceptor aircraft!' Aircraft: 'This is a United States Marine Corps F-18 fighter. Send 'em up, I'll wait!' Air Defense Radar: (no response .... total silence)
