Kate Middleton Sits At Fighter Jet Cockpit In Amberley Air Force Base Visit (PICTURES)

Kate Middleton ignored a suggestion by Prince William to "jump in the back" of a parked fighter jet and jumped into the front seat, during a visit to a Brisbane air force base.

The Duchess of Cambridge jumped in the Super Hornet jet at the Royal Australian Air Force (RAAF) base Amberley near Brisbane - with the Duke of Cambridge's line "do you fancy jumping in the back?", having fallen on deaf ears.

William, a former RAF search and rescue pilot, had to be content with being a back seat driver and sat behind his wife.

It is believed to be the first time the Duke and Duchess had spent a night away from their son Prince George attending a public event, during their tour of Australia.

The royal couple's visit to RAAF Amberley also saw the Duke and Duchess acknowledge Australian servicemen killed in recent conflicts.

They spent some time with the relatives of four Australian servicemen who lost their lives in the Middle East.

William and Kate met the families of Lance Corporal Stjepan "Rick'' Milosevic, Trooper David Pearce and Private Matthew Lambert, who were all killed in Afghanistan, and Flight Lieutenant Paul Pardoel, who died in Iraq.

Speaking ahead of the visit, Air Commodore Tim Innes, Senior Air Force Officer at RAAF Amberley, said the meeting would mean much to families still struggling with an enormous sense of loss.

He said: "That's an extremely important point about the visit. That is a big part of why they are visiting the base - to honour those fallen and those who made a sacrifice in Afghanistan and other conflicts around the globe.''
