Do you seriously think their Airships were given the option of saying no? And what would the RN have done if "requested" to mount a sail-past up the Thames? And no doubt, despite real overstretch in the Army, there will be plenty of troops on parade for Trooping the Colour. Come on, live in the real world. We all have the same job to do for the same Master. Let's not waste our breathe on this inter-Service rivalry cr*p, even in jest.
