Arrived at LGW this evening but our stand was not empty. So we stood for 11 minutes with both motors (DHC-8 Q400) idling all the while. What a fabulous waste of gas and increase in pollution. The airports have, almost universally, been allowed to book in more flights than they can handle. The amount of time spent in the hold and taxi to/from the active is massive but no one is going to change it.
It looks as if long haul towing will have to wait for a system that puts the motive force onto the mains, not the nose gear.
