Phil asked, "What is the bandwidth of a 747 ..."

I talked to the Boeing folks here in DC.  A B747-200F
(cargo config.) has:  gross take-off wt. 416 tons
                      operating wt.      171
the difference being fuel and cargo wt.  245

Allowing 45 tons of fuel for 6 hours enroute plus reserve 
leaves 200 tons of compact disks.  According to Cerf, 

100 disks  equals  50 pounds  equals  7.8*10**12 bits; therefore,
multiplying by 8,000,
800,000 disks  - 200 tons - 6.2*10**16 bits
dividing by (6*3600)  21,600 seconds equals 2.9*10**12 bps.
