When I saw those all those aircraft my first (joking) thought was that such an aerial raid would use a measurable percentage of North Korea's daily fuel allotment.
I then had to look it up.
North Korea uses 15,070 barrels of oil daily (ranked 146th in the world)
http://www.eia.gov/countries/country-data.cfm?fips=KN
15 070 oil barrels = 2,395,938.53 liters (Google)
(1 oil barrels = 158.987295 liters)
I am assuming those aircraft are similar to An-12s and there were a dozen on them.
12 aircraft x 18,100 liters per plane = 217,200 liters

So that flight alone would take over 9% of North Korea's average daily heavy fuel consumption.
2,395,938.53 liters/217,200 liters = 9.065%
