Yes. Although commercial carriers are available, missionaries have previously experienced extreme difficulty with conducting Bible Camps, Vacation Bible Schools, and building projects because of the cost of commercial carriers.  There are no roads connecting the vast majority of villages that pepper Alaska’s 570,374 square miles.  The only practical way to get Gospel into the villages by way of personal one-on-one evangelism is with an airplane.  “How shall they believe on Him of whom they have not heard?  And how shall they hear without a preacher?  And how shall they preach except they be sent?”  (Romans 10:14, 15)  The next question begs to be asked!  “In Alaska, how can the preacher be sent, without an airplane?”  As the young colt carried Christ into Jerusalem for His Triumphal Entry, so do planes carry the Gospel of Jesus Christ into the villages of Alaska!
