We may know each other....
The charter was for a ten ton (10,000 kgs) crane motor... so priced and dispatched on 4 engine tprop capacity 15,000 kgs.
On arrival - having booked forklifts, hi loader etc etc. man in small van turns up with a smallish wooden box weighing about 500 kgs..... yep its a motor FOR a ten ton crane. Oh well.
Or the time a major cargo company chartered the same machine to fly an empty envelope 300 miles..... they needed a crew moved , no pax aircraft available at such short notice but we could take their staff as jumpseaters on a cargo flight, problem solved.
