Conversation overheard on the VHF Guard (emergency) frequency 121.5 MHz while flying fromEurope 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 FA-18 fighter. Send 'em up, I'll wait!' Air Defense Radarno response .... total silence) God Bless our troops!
