The latest attempts to account for the passport check fiasco - 'the wrong kind of rain' being the best one to date - raise a number of awkward questions, not least among which should surely be who authorised the purchase and installation of an assortment of automatic scanners which are, frankly, not doing the job.
'The difficulties were exacerbated by a series of technology glitches including the failure of a finger print machine, used to check passengers who require a visa to enter Britain.It's clear that this new technology isn't up to the task - and that the travelling public has not been given sufficient time and incentive to adopt the new system. Last month, I watched a mere handful of people successfully negotiate the vast array of gates in a local airport while everyone else queued up for half an hour.
On other occasions both the iris recognition and new automatic passport scanning gates failed, adding to the frustration of new arrivals.'
Meanwhile, the shortage of UKBA personnel is surely due to shrinkage, in the expectation that all of the estimated 50% of Britons with biometric passports (issued or renewed in the last 5 years) would use the automatic gates - the sort of misconception that has 'statistician' stamped all over it.
It has all the hallmarks of a rushed job; a lack of clear information, malfunctioning equipment and an apparent failure to consider the possibility that travellers are unwilling - or unable - to separate from companions who do not qualify to use the machines.
The Olympics, of course, provided the catalyst; like one of those home makeover programmes, the installation was completed against the clock and doubtless looks great in some company's publicity material - never mind that the tin-foil is already peeling off the pelmets and the curtains are coming unstitched.
And yet, amid the outcry, there has been almost no reference to either technology or staffing policies. Instead, we have blame heaped on incomplete flight manifests, late and early arrivals and now the British weather.
This suggests two things to me; firstly, someone has made a great deal of public money out of supplying this machinery, possibly someone important and powerful enough to discourage any suggestion that it is at least a contributory factor.
And secondly, no-one* is paying the slightest notice to what I have to say.
*Apart from JuliaM, that is, who sums the matter up in admirably laconic fashion.
