Scientists from all stream s should sit together and study the video where in Saudi Arabia Alliens put their craft airborne and probably trigger evaporation of their one partner who accidentally left behind and got noticed so in very late stage of flight. 

Physics specialists should work with aerodynamics specialists how to put in use the suction pressure to propel and navigate an air machine. This suction pressure is powered by nuclear powered turbines. It suddenly takes the momentum of say thousands and thousands horse power. 

cluster bombs if put with nuclear bombing technology through space driven missile system will be able to neutralise their advantage factor to strike earth with nuclear bombs.

In space parlains there does not exist any thing called should have but the enormity of their base is something which is a question mark to earth existence. 

Critical of advantage factor with earth is that earth have more resources and near at hand whilst they are far far to their origin. 

They have extremely developed computing systems of their own that is probably better to earth one.
