F-35: vertical landing

a quote form another part of the site:

” A US Navy report from the Naval Facilities Engineering Command published in January says that the jet efflux will “melt the top surface of asphalt pavements and is likely to spall the surface of standard concrete pavements” and that there are “no identified sealants that can survive a significant number of vertical landings”. It recommends that vertical landings are only made on specially designed continuous concrete pads (with no joints) of at least 100ft square.

A similar report published by the US Navy in November 2009 said that aircraft carrier decks will require significant strengthening to withstand the risk of buckling under the high temperatures generated by the F-35B.

So the vertical landing and lift off capacity of this yet can’t be used in practice?!

Is anything on this thing working as it should?
