This will be sufficient for the stealth jets to carry out short takeoffs and vertical landings while protecting the road beneath them.&amp;quot;&lt;p&gt;They did this before as part of an airshow demo. The Royal Engineers (Army co-operation!) had built pads at RAF Fairford for RIAT then the F-35B flew in, engaged STOVL mode (i.e. lift fan door open, rear engine nozzle pointed down etc.) and landed vertically on it then took off again.&lt;p&gt;Can&amp;#x27;t remember what year it was; Google suggests the MoD released PR saying they had done the same thing at Marham in 2018 but it&amp;#x27;s possible the demo was by a USMC F-35B.</text><parent_chain><item><author>sillywalk</author><text>&amp;quot;FTA:
