Wiltshire - "It was like a Guatemalan sink hole had suddenly gorged itself on our lovely 1966 Airstream Overlander International," distraught US sightseer Joyce Hooley told reporters today.
"One minute it was right there where we'd parked it and the next it had vamooshed - swallowed up by a 500 foot wheat field etching of a BP Deepwater Horizon oil rig.
"Someone please tell me this is not some sort of horrible anti-American tourist hoax."
Mrs Hooley and her husband Brad, retirees from Red Neck, Indiana, were vacationing in Wiltshire when they decided to visit some of the bizarre crop circles reported in the 'Oddball' columns of local newspapers back home.
The couple recall driving into the center of a particularly imposing crop circle that they claim is at the core of a 'black hole' mystery after it 'swallowed up' their customised caravan.
"We'd followed the season's amazing crop circle pix," Mrs Hooley told the Alton Barnes Morning Advertiser, "especially that one of a ganja pipe-smoking alien which my husband wanted to photograph for the family album.
"Now we're homeless in a foreign land - all our belongings, travel documents, money, personal ID etc sunk without a trace."
The Hooley's story is being investigated by the local police service following an official complaint of theft and/or illegal appropriation by person or persons unknown.
The couple's request for helicopter-guided thermal imaging equipment to scour the countryside has been noted as lodged amid increasing local panic of other 'inexplicable' mobile home thefts.
A police appeal for witnesses has so far drawn a big blank.
