JO, you talk of using the King Airs and Citation to get to remote areas, we too fly to remote areas but we don't require 5,000ft runway to land either one of these aircraft, last time I checked this was a requirement for TC to land these types according to their SOPs,{ has it changed?} however if TC wants to build 5,000 feet of black top at a few remote spots, I can think of a few operators who would be very grateful for such improvements!
