Once the bag was stacked with others in the container, unless Sky were VERY lucky there'd no longer be a shot available when it was loaded on the plane--there's every chance the lens would be pressed up against the next suitcase and, once closed, the inside of the container would be dark.
Assuming Sky only had funds to splash out on a short haul flight I assumed the bag would have been hand loaded onto the aircraft, thus providing a nice exterior shot as it traveled up the conveyor?
Yes, its not quite clear if it was a test day although the passenegrs in the que have a lot of luggage and look the part....
No mention was made of the date the bag took its trip which is strange.
