Hoovers is a reliable source--AirSea Charters, Inc., is listed as a company providing transportation services using boats, no mention of the planes, weirdly. President listed is John Rogers and principle is James A. Rogers. Address and phone number: 1809 N 132nd Avenue Cir
Omaha, NE, 68154 United States (Address is a house in residential area.)
(402) 206-6862 † (they have the symbol of the crucifix a few places). No longer a working number and company did belong to deceased pilot John W. Rogers. The Christian tie-in, again, is interesting.
