"What we need is the thermal imaging and that looks like it can only be provided either from the Central Greek government.
"There is no sign of them having that capability I have to say. We do know that there are four UK bases on Cyprus, they would be the easiest to scramble politically but they're about 600 or 700 miles away.
"Only 70 miles away in southern Italy there is a defence capability there with this thermal imaging ability on the helicopters and this isn't the time for niceties - we just need to get on with it.
"The weather is likely to change sometime today we desperately need to get a military helicopter with thermal imaging capabilities out there looking for Roger immediately."
"We're really grateful to the Greek authorities for their help so far. We are however aware that their resources on the island are fairly limited, so we have paid for a helicopter to help with the search.
