Mr Jamieson, someone left it at work on the desk....honest!
CaptAirProx,
Definately not cobblers!
The aircraft in question called mayday on climbout after getting a warning that the cargo door was open....now whether or not it was a false warning, I don't know, but he came back in a hurry!
Also, it wouldn't be the 1st time that I've seen an aircraft leave the stand with a hold door open, although I doubt that was the case.
