Posted this elsewhere but what the heck
Was a pax in a UAL boeing 777 a while back taking off from LHR if I remember correctly. I had the privilege of listening in on all the radio transmissions in the pointy end. We were only a short time into our taxi run when a female ATC's voice came over the radio
"Flight xxxx. Are you ready for takeoff."
I was feeling eh slightly alarmed in the back of the aircraft upon hearing this.
Captain who couldn't resist a sarcastic reply retorts:
"We will be when we get there"
