	well... here are the numbers (using LTO-5's)


	you can do the math.


747-8 -- 308647 lb  /  8130 km 
747-8 -- 600 cubic meters

lto-5 -- 3.0 Tb
lto-5 -- 0.6 lb
lto-5 -- 11.3 x 2.79 x 11.1 cm


	and althugh its not generally available,  the LCF has 4x the load of the 747-4f

	the killer is going to be the 280m/s write off the tapes. :)
