GIB is well known to become enveloped in sea fog, have it clear, only to become re enveloped in it just as fast (think JER). So with that in mind would you wish to have been kept on an aircraft, finally got airborne, overtaken the BA busses, only to have to re-divert again to AGP? I can see why BA made the descision they did and how it turning out too be a bright and sunny afternoon made them look perhaps a little silly, but either way on the one time it happened to me it never took 4 1/2 hours to re-arrive at GIB on the coach. Were they taking the toll road or that back lanes?
