Its' a helicopter thing !
This is typical of the heilcopter mentality, last week a heilcopter turned up on a private strip that I know and hovered above the runway, the result was a fixed wing had to go around.
The fixed wing then made an aproach to the other runway and................... yes you have guessed it the helicopter moved to that runway and another go around resulted.
It is quite clear that the helicopter pilot had no idea that there was another aircraft trying to land.
The next helicopter that lands without permision or good reason will have a big chain put around the rotor head and be charged £500 a day parking, the chain will not be removed untill the fee is paid in cash.
