You are correct:

Two-man rule

Main article: Two-man rule

A Permissive Action Link (PAL) is a security device for nuclear weapons.

These two locks are part of the implementation of the two-man-rule in a Minuteman ICBM launch control capsule.
Modern PALS use the two-man rule, which is designed to prevent accidental or malicious launch of nuclear weapons by a single individual.
For example, on a ballistic missile submarine (SSBN), both the commanding officer (CO) and executive officer (XO) must agree that the order to launch is valid, and then mutually authorize the launch with their operations personnel. Instead of another party confirming a missile launch as in the case of land-based ICBMs, the set of keys is distributed among the key personnel on the submarine and kept in safes (each of these crew members has access only to his keys), some of which are locked by combination locks. Nobody on board has the combination to open these safes; the unlock key comes as a part of the launch order from the higher authority.
In the case of Minuteman missile launch crews, both operators must agree that the launch order is valid by comparing the order's authorisation code against a code from a Sealed Authenticator (a special sealed envelope that holds a code). The Sealed Authenticators are stored in a safe that has two separate locks so a single crew member cannot open the safe alone. Both crew members must simultaneously turn the 4 launch keys. An additional safeguard is provided by requiring the crew in another Launch Control Centre to do the same for the missiles to be launched.

Supported Palace for over 69 years since the age of 7 and have seen all the ups and downs and will probably see many more ups and downs before I go up to the big football club in the sky.

I think you missed the tongue in cheekness of my post.

The Tories have done a great job looking after my injured and wounded fellow marines and Jonny Mercer MP here in Plymouth is champion to ALL ex serviceman and does a fantastic job all over the country. With Corbyn its all talk as it was with Boy Blair and Brown. They could not look after themselves let alone servicemen ...apart from sending the poor blokes to war under a false banner ???

We have been here before, Red Wedge?

The problem seems to be that whilst the Labour Party may be the biggest in Europe, they do not back the leader 100%. You are still talking about a marginal amount of people, assuming the young can be bothered to register and then be bothered vote.

We will get a better idea once the manifestos are released but Labour, unsurprisingly, have already come under scrutiny regarding their figures.

Since Corbyn became leader, the membership has nearly tripled. I would say that the vast majority are on side. Youth voter registration is also at record levels, which again is fanatastic news for democracy.

As for the spending, you have to ask who is asking the question about Labour's figures? Surely the Tories need as much scrutiny, particularly considering that under their leadership, borrowing has gone up, debt has gone up, tax cuts have continued and government subsidies to private companies in infrastructure, the health service, education etc etc have only exacerbated? Yet no one seems to question where the money for this is coming from. Funny.

By contrast, Labour will have a fully costed manifesto, and the promise of a National Investment bank and targeted sectors for government borrowing put them in s different league to the Tories in terms of economic accountability and detail.

If punk ever happened I'd be preaching the law, instead of listenin to Lydon lecture BBC4

Average pay is lower than up to 18 years ago. It doesn't look like wages are going up any time soon. Well for the vast majority anyway.

Still we can afford wars.
