The couple recently moved from their home in Richmond, south-west London, to spend a year living in Prague, where Mrs Allen has been anxiously awaiting news of her husband from the other side of the world.Mrs Allen explained that while her husband has got lost several times in previous expeditions, he has not done anything 'reckless' since settling down and having children.'He has been so careful since I married him.The Yaifo is thought to be one of the last people on Earth to have no contact with the outside world.
The 57-year-old was been found 'alive and well' near an airstrip 20 miles northwest of Porgera, Enga Province, four days after he was reported missing.In a blog post on his website in September, Mr Allen described the Yaifo as 'one of the last people on the entire planet who are out of contact with our interconnected world'.'In October I'm hiring a helicopter to drop me off at the abandoned mission station, Bisorio - a forlorn place,' he wrote.'Last time the Yaifo greeted me with a terrifying show of strength, an energetic dance featuring their bows and arrows.'On this occasion who knows if the Yaifo will do the same, or run off, or be wearing jeans and T-shirts traded eons ago from the old mission station.'He said he did not have an obvious means of returning home and either had to paddle down river for a week or so, or enlist the help of the Yaifo.'Just like the good old days, I won't be taking a sat phone, GPS or companion.Or anything else much,' he wrote.'Because this is how I do my journeys of exploration.But you can be sure my wife will be giving him a severe ticking off.' Mr Allen's agent Jo Sarsby said: 'At 5pm local time Keith Copley, the coordinating director for New Tribe Mission in Papua New Guinea confirmed in writing that Benedict Allen was safe, well and healthy.'He is presently located at a remote airstrip 20 miles northwest of Porgera, Enga Province.'Confirmation on exact location coordinates are now being confirmed in order to arrange evacuation as soon as possible.' Speaking to The Sun, Mr Copley said it will take 'at least a couple of days' for Mr Allen to get to a point where he can be rescued.'The problem we have is that communication is really bad so I can't physically speak to him, so the locals he is with are trekking two hours to make calls to me.The adventurer's friend, BBC security correspondent Frank Gardener, who previously travelled to the southwestern Pacific island with him, wrote today: 'This is exactly the sort of challenge he thrives on.'But as well as having to contend with almost impossibly steep and forested terrain, it seems his plans have been disrupted by an outbreak of tribal infighting which often happens in remote areas.'Although foreigners are rarely the target of this violence outside the towns, there is always a risk of being associated with one tribe that is at war with another.' Meanwhile, Mr Allen's brother-in-law said today he will be met by a 'severe ticking off' from his wife and close relatives once he is back in Europe - but they are all thrilled and relieved that he is safe.
