Now back on track, why would the second carrier aircraft take off before the first? Unless I misunderstood your post my idea would theoretically work.

well, i don't think there is a time trigger between first and second plane ( takeoff) but rather certain position of first plane .... when first plane leaves the runway triggers taking off start for second plane .
So if you place trigger before reaching end of runway ( first plane) to get shorter takeoff intervals it would affect carrier taking off .... IMHO

p.s. i do hope i'm wrong here ...
