If im not mistaken, the current US carrier ( US Essex? ) is made up of 4 major blocks that are NOT easy to edit... so if we want to make an object 2x the size were looking at a lot of work o.o
Lines to slow down jets are a nice idea, IF and ONLY IF there is a map where we have a custom carrier and IF they are even possibly ( hardcoded

)
Personally I would be avoiding making a map with a carrier and .6 jets, though it is very possible to land on the carrier with a jet ( Going FUCKING slow as hell trust me you can land anywhere ) .... its nearly impossible to back up ( Ok im going to back up now... la dee la, throttle down ZOOM! ) and nearly impossible to find the re-arming sweet-spot even on maps like kashan.
Good idea, lots of work. imho
