Not really. I think it's perfect size. It's also got a heli pad on the back for testing my Trainer Aircraft. I built the back section separately from the ship. I landed one of my Banshee trainers on the pad alone.
That has been confirmed to be a real video. It's possible as the F-35 has the TWR is high enough with the Afterburner (Which if you look is activated when the technical problem occurs)
