Thread drift, but to follow up on fujii post.
Some highways have areas set aside for runway usage. In the old days prior the pilot would call a truckie on CB and get him to drive down either side of the highway for a nominated distance and knock down all the timber white posts.
And at night by car head lights. Both PC-12 and King Air, it's all single pilot. Normal crew on our local King Air is pilot plus nurse, and only if the particular case calls for it, a doctor. Book "Australian Midwives" by Paula Heelan is a compendium of tales written by various nurses employed in the EMS fixed wing services. Good yarn.
