Butler National Awarded Contract With One of the Largest Aerial Mapping Firms In
South America

OLATHE, Kan., May 5, 2011 /PRNewswire via COMTEX/ -- Butler National Corporation
(otcqb:BUKS - News), a leader in the growing global market for structural
modification, maintenance, repair and overhaul (MRO) has contracted with Horizons
South America S.A.C. to install provisions for advanced aerial cameras & sensors
in its fleet of aircraft.

The new installation will allow the Horizons fleet to deliver dual sensor data
acquisition technology for mining and oil companies in Colombia and Peru.

Alejandro Talavera, CEO of Horizons South America S.A.C. said, "The aerial data
required to meet simultaneous acquisitions under the same weather conditions for
environmental studies is very rigorous. Butler National's sophisticated dual
camera STC package allows us to meet these criteria."

Craig Stewart, President of Butler's Aerospace Division, added, "We continue to
focus on international business as a key growth driver for the Company. This
installation builds on our existing relationship with Horizons that includes a
dual camera provision on its turboprop twin-engine aircraft. We are the only
aerospace company in the world that holds the FAA Supplemental Type Certificate
(STC) for this type of modification. Today, we hold more than 250 STCs which are
a significant barrier to entry in the MRO industry."

Butler National's presence in South America is one of many international projects
underway as the company continues to strengthen its leadership in the global MRO
marketplace.
