Supporting air operations from a full fledged military airfield is itself a massive and complex task. Inspite of everything available readily, it is challenging to achieve desired tempo of operations. Requirement of spares, ammunition, fuel, repair facilities etc isn’t easy to create, near a motorway, in same manner as inside an airfield. Then there is also availability of trained spare manpower in adequate numbers to carry out these tasks.
Doing same from Motorways or Expressways has severe limitations. It can just help in making aircraft land if home airfield is bombed. That’s it.
Due to depth, India doesn’t have much use to this philosophy. It is in the last decade or so that IAF has carried it out, that too in a limited manner. It is unlikely to gain prominence like PAF.
The tweet claiming that SU30 could not land is nothing but a joker trying to generate happiness out of nothing. Fighters were planned to do exactly what is seen in the video. But for a PAKjeet……..
