Dear H.D.,
As it appears that you can now bend flight paths (not to mention the system) for the benefit of Ms BS ....
I think that we have the ideal way to fix the noise pollution problem AND the shortage of cash for NATS.
Anyone should be able to chose to have their own private air show! Upon payment of the correct amount, an entire morning/afternoon's worth of flights will be routed overhead!
This deals with noise pollution as everyone gets an even amount of it and no one can claim to suffer from Airport Blight, because
everyone will have it
Those able to pay more, can have larger aircraft on display, with special rates for The Lady herself, of course.
When business is quiet, you could run 'specials' like throwing in a Tupolev or something. Very popular will be the Mystery Package, when you will not know what you are getting until it arrives.
Not to mention that, when I pay for my special display with my AmEx card - just think of all the frequent flyer miles I shall earn, all without moving from the garden
