Love this "combat landing" crap when has anyone EVER seen a tanker land or depart from a dirt strip? They use civvy or mil runway that have been taken over (Balad/BIAP/KABUL/BRIZE (sorry had to add that last one) Tankers dont do that we all know that approaches might be a bit funky but not out of stress limits..... so selling an airframe as combat ready is pish (DAS aside). Buy a good tube as the yanks have (bloody old 707) and fill it with gas and a delivery system job done. Sometimes KISS works. For all those who dont know KISS= Keep it simple stupid.
