Waiting on an engineer

So right now I should have been happily on Brisbane seeing family instead I'm stuck at Proserpine airport with a cafe that is running out of food while we wait for an engineer to fly two hours to check a 'non important flap' instead of sending a new plane they are flying him in when he could very well say the plane can't fly! This means that we will all be stuck another 2 hours while a new plane comes in. We have now been told we have to wait another hour for the engineer to arrive before we can even re board no offer to get us on another plane or anything! Done their dash!
