Re: Dreamlifter Loses a Wheel in Italy

It doesn’t look like the wheel came off. It looks like the tire failed, and what you’re seeing is the tire carcass falling to the ground. If the wheel assembly had separated/failed, it would have done so during the takeoff roll.

Re: Maintenance Coffee Maker and Boiler

If no oil was added for the prior leg, and was entered as serviced when it wasn’t, then at the end of the next leg, oil would be added for both legs, but the flight tim...
