Re: ROTFL I mean SRVL
"If you can get a 20 tonne fighter to fly at 35 knots just using slats and flaps you crack on."
Easy. Just make the wings a bit bigger. The induced drag saving from abandoning the weight of all that lifting-fan gubbins will more than compensate for the higher form drag, not to mention maintenance downtime - compare notes with any F-35A operator.
But don't change the subject. You can't update the principles of aeronautical engineering just by changing what you call it, and slagging off people with long memories. The F-35C is still a ridiculously expensive way to deliver the same STOL capability available from the F-35B.
