William and Catherine's Helicopter Ride

William, Catherine and Lupo were photographed taking a helicopter ride with their friend from their home in Anglesey, North Wales to an aerodrome on the outskirts of London following a 200 mile flight. 

(Below you can see Catherine looking out at the top right corner of the right window.)

The Cambridges arrival was photographed by a surprised couple watching light aircraft taking off and landing at Denham in South Buckinghamshire who shared their reaction in the Daily Mail story:

'We had no idea it was the royal couple at the time. We had a look at the photos on our laptops a few days later and realised that it was in fact Prince William and Kate. It's amazing to think that we saw the royal couple without any crowds around them. They were like any other couple out with their dog - albeit having just been flown in by helicopter. Lupo was very behaved. Kate let him down on the grass and he stayed close, although you could see he was excited'.

The orange McDonnell Douglas helicopter carrying William and Catherine belongs to a friend of the couple's, Timothy Oliphant-Hope who is managing director of Shoreham based Eastern Atlantic Helicopters. Mr. Oliphant-Hope was behind the controls and said he occasionally gives the couple a lift "when he is routing past North Wales, if it is convenient for all parties".

Catherine was casually dressed in her grey wool Zara tweed jacket. The military wool garment features gold buttons and is thought to be from the brand's 2011 collection. The Duchess was photographed wearing in last month during a shopping trip to Design Centre Chelsea Harbour. She also wore a loose fitting black top underneath.

Catherine's jeans have been identified as the Topshop 'Leigh' Maternity Jeans. The medium-rinse skinnies are crafted with a tonal band to accommodate a growing bump for supportive comfort. They're available for €61 at Nordstrom.

Catherine opted for comfortable footwear - her Mint Velvet Taupe Suede Plimsolls.

Catherine carried her Tod's D-Styling Bag, an accessory she has reworn several times.

Upon their arrival in Denham, William drove off in his range rover while Catherine and Lupo left in a separate vehicle. It was not revealed exactly when the photos although it is thought to be the last week in May.
