My story is post flight - just.
Many years ago with a full load of pax - 737 from a certain small antipodean airline touches down.
Speed brakes pop up as they do.
Sharp eyed passenger notices large spanner wedged in a cavity before they drop back down!
I kid you not.
I was in the airline
PR department at the time and we got a frantic call from the fleet manager telling us what had happened in case anyone went to the media.
Quickly removed by the lineys - and not a single journalist was any the wiser.
Now, I could relay another story about how a spilled cup of hot liquid on the flight deck forced the landing of another jet full of parliamentarians - but they did find out about that.
Very droll headline from that one.
