RAF in terror swoop on 2 plane spotters at Odiham in Hampshire

They were waved through a military checkpoint and began taking pictures of helicopters.

It took top brass ten minutes to twig the security breach as salesmen Max Awad, 30, and Addison Bridet, 29, snapped away at Chinooks and a Lynx.

An armed response team was scrambled at RAF Odiham, Hants, to take them down.

Last night Max, from Basingstoke, said: "We had no idea we'd done anything wrong. At the checkpoint there were loads of cars being let in. I presumed they were having some sort of open day.

"I'm a massive plane enthusiast so I said, 'Come on, let's go and have a look'.

"We drove up to three helicopters on their landing pads. We got very excited and got out to take pictures.

"Suddenly I realised it wasn't an open day ? there were no refreshment stalls. Then all hell broke loose. There were armed guards running everywhere and a tannoy blaring, 'emergency, emergency, breach of code'."

The pair were locked up for three hours and interrogated before being released.

The MoD said: "Security was not compromised."

Police 'want terror powers delay'

 By Robin Brant Political Correspondent, BBC News  Control orders were introduced under the former Labour government in 2005 Counter-terrorism police are not ready for the introduction of new laws to replace controversial control orders on suspects, the BBC understands.

The bill which would create Terrorism Prevention and Investigation Measures (TPims) is due to pass its final hurdle in Parliament on Wednesday.

But some senior officers have told the BBC they still feel they are not fully prepared and a delay is necessary.

The Home Office said "extensive preparations" were ongoing for TPims.

TPims are due to come into effect early in 2012.

Eleven people are currently subject to control orders. Their movements and their access to communications are severely restricted because they are deemed to be a threat to national security.

But the law is changing, following a commitment in the coalition agreement to "urgently review control orders".

End of relocation

The Liberal Democrats pushed for changes to some of the most restrictive conditions which they viewed as an intolerable breach of civil liberties.

One of the biggest changes will be the end of relocation, which gives the authorities the power to force suspects to move away from their homes and close associates. This applies to most of the current orders.

The police and MI5 have been given more money to pay for extra surveillance under the new system and about 100 new agents could be recruited.

But the BBC understands that some senior officers at Scotland Yard who deal with counter terrorism feel the police are not ready for a January start.

They want a delay of several months.

So far the government has been asked to extend the transition period by just two weeks.

This echoes concerns expressed in June by then Deputy Assistant Commissioner Stuart Osborne, who told Parliament the Metropolitan Police needed "more than a year" to get the resources and people in place.

A Home Office spokesman told the BBC that "extensive preparations were being made for transition to the new TPim regime".
