I would guess that 700 miles is possible in a smaller plane, but then I'm not a pilot. That would be about 7 hours of non-stop flying though, which may exceed a smaller plane's capacity.

Muslims in Britain want greater recognition of their faith with the introduction of Islamic law for civil cases and time off for prayers during the working day, but are equally committed to greater participation in British life.
A special Guardian/ICM poll based on a survey of 500 British Muslims found that a clear majority want Islamic law introduced into this country in civil cases relating to their own community.
Some 61% wanted Islamic courts - operating on sharia principles - "so long as the penalties did not contravene British law".
