Amazon
This development, together with the news that they are to build a 1.3 million sq.ft. hub close to East Midlands (which I believe will become their largest UK fulfilment centre) and news of similar projects at/near airports in the States, perhaps adds more weight to the rumour that Amazon are about to launch their own in-house airline/overnight cargo operation to compete with UPS, DHL etc.
An announcement is supposedly due in 2016.
