As an ex immigration officer and PPL holder flying out of Headcorn, it is disappointing that the BBC have done this.It is nigh on impossible to staff every airport in the country with an immigration/customs presence - the powers that be are too busy trying to staff the major airports as it is. Several weeks ago, we had four illegals brought into Headcorn on a Saturday morning from Belgium. Thanks to the vigilance of our ATC, the illegals were spotted getting out of the plane and walking out of the airfield. The owner of the airfield managed to get the illegals to come back to the airfield long before the police and and UKBA turned up. I don't mind UKBA being taken to task but the knock-on effect on the cross channel movement of GA traffic which is easy enough at the moment could be made a lot harder. Already UKBA senior officials are taking more than a passing interest in movements in and out of Headcorn. On this occasion the least the pilot should have done was to take the passenger(reporter) to ATC to show his passport.
