That s clear. But in SBF they wrote that spheroid dropships could Land on paved hexes only. It Is clearly an error.
On page 182 of Airship and Spheroid Landing: Airships require a landing area that is comprised of either clear,
paved terrain or a hex predesignated as having an active runway.
All
other spheroid aerospace Squadrons may land upon virtually any
terrain of uniform elevation—including clear, paved, woods, jungle,
or even urban hexes. However, the act of landing in upon any terrain
other than paved will cause terrain damage, and may result in damage
to the landing Squadron as well.
Sometimes the rules require a second or third run over. Unless you can point out the restriction as paved only for Spheroid, this is the only SBF rule for Spheroid landings I could see.
