VTOL is a helicopter. Trying to turn a forward-thrusting jet-propelled airframe into a vertical ascent-descent is an exercise in futility, until we develop a reliable anti-gravity platform, and the physics just are not there yet.
Contact the engineers behind the development of the S.H.I.E.L.D strike force. I know that is real because I see the series on TV....
You young pups think you know everything. Try Googling the Hawker Harrier from the mid 1960s. VTOL has been around for half a century. Longer than that if you go back to the Kestrel.
