Number of containers in US last year = 6,000,000
Shipping container, average cubic capacity approx 70m
Traveller tonnage of shipping container 70/14 = 5 displacement tons.
Number of containers carried by a far trader = 13
Number of containers carried by 20,000 ton bulk J2 frieghter = 3000
Number of visits by Far traders to handle US cargo = 461000 or 1200 per day, 50 per hour, almost 1 per minute.
Number of visits by 20,000 ton bulk frieghters to move same load = 2000 or 5 per day, one every 4 hours.
The whole of the world will easily triple this lot.
That means if 90% of our world shipping is handled by the big lines we will be having 14 bulk frieghters and 300 Free and Far traders a day in our skys.
This is only an approximation and is not exact nor does it include air shipping and non container cargo such as liquids/gases/ore/grain etc.
That is a lot of ships in the sky !
