Suborbital capabilities
An Aeris 3A with an FL-400 fuel tank in place of one of the fuel tanks and a ram air intake mounted on the top with a tailpiece is capable of suborbital flight, exceeding those of the Aeris 4A (with my mediocre skill), up to 150km.— Preceding unsigned comment added by Thompcan (talk • contribs) 15:51, 15 May 2014 (UTC)
