The most obvious outcome of all of this will be new rules, regulations and expense for those who operate a private aircraft with little or no benefit to the public at large.
The Goverment will do anything just to be seen to be doing something to protect the people.
As we have seen recently to members of pprune that it is us that need protection from the public not the other way around. ( refer of course to the attack at Redhill recently).
This does not absolve us of any responsibility.Simply taking the keys out of the aircraft would probably suffice.
Should one idiot (say a drunken one) get through the tight airfield security
start and crash a plane - then we will all be obliged to take the propellors off and take them home with us!
Let us be serious for a moment.If an attack does happen in the UK ( and personally I think it unlikely) it will not be by light aeroplane.It will be by a truck on Oxford street on a Saturday Afternoon or a bomb on the Undergound at rush hour. Or something equallyhorrific.The government know this but don't labour the point so as not to alarm people. So statements get made about stopping light planes crashing into Parliment - it doesn't affect many people.
BTW It seems our wonderful Scottish Parliment building is to cost a few million more (Up from 300 million!!!) to make it bomb resistant!
