Yes there are Videos of two F35B's flying off USS Wasp, my concern is that the pictures of their take off showed them using the full length of the deck to take off from with a very light load.
What we don't want to happen is that any more weight gets built into the Bs as regards the front wheel, it was designed for vertical landing and if the RN for very good reasons needs to to rolling landings is it up to it or for rolling landings to be safe does the B need a similar set up to the C, double wheel etc? Making any British B's different from any USMC B's...
Using rolling landings as I understand it makes use of a rather different skill set to plain vertical landings, more akin to classic carrier landings I would have thought.
