bjcc,
I'm not sure if you're aware that a large proportion of the flight delays now are because more hold baggage has to be checked because the scanners are detecting laptops, ipods etc. It was quicker to check them with a handbaggage check.
I don't know why you defend the indefensible. This plot was apparently known of for some time, preparations for a/c security should have been pre-planned thoroughly, not this half-baked, last-minute c**k-up.
