The SLUF and 'toom flew with wings folded.
The Tomcat could fly with asymmetric sweep.
So even in the event of pilot error, or some type of mechanical failure, surely there's no in flight worries about the new triple 7's last three metres on each side?
I'd be more concerned about the person sitting in Seat 0A forgetting to fold `em coming into the gate, and trading paint with someone or something else.
And no doubt there'd be all sorts of alarms and things to stop that happening...
