Replacing a 'b' with a 't'

Amidst all this talk of billions and trillions, I feel it is a worthwhile exercise to attempt to comprehend the meaning of $1 trillion. A friend of mine recently sent me the following.

How many transport flights it would take to move $1T worth of $100 bills?

So $1T is 10B $100 bills.

10B grams is 10M kg 120,000 kg is the capacity of the C5 Galaxy aircraft.

So it would take 84 flights to move $1T in $100 bills.

The Galaxy C5 is not a small aircraft.
