I would estimate that approximately half the passengers were sitting at the gate for our flight home when it was cordoned off and those inside invited to stand outside the gate.
Security tables and equipment then appeared and everyone was given another security check which consisted of a passport check against the passenger list, a body search and a fairly thorough hand luggage search.
Now I am all for security, but if something had been found at this stage, surely that would mean that all the previous checks were superfluous.
