document.write( "The pilot's distance to the horizon is a leg of the right angled triangle, whose hypotenuse is  (6371+6) = 6377 kilometers,\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "and the other leg is exactly the Earth radius of  6371 kilometers.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the answer is   = 276.5 kilometers.\r\n" );
