MiG-29s are able to operate from grass airfields. They have a special intake design that doesn't suck dust on takeoff.

BTW, in 1993 when USAF F-15s visited VVS training center n Lipetsk - they refused to take off from the dirty airstrip. They had Su-27 taking off before them to sweep the airstrip.

Not sure but it could work.

From what I know and have learned you are partly correct, the Inerstate Highway was not set up specifically for that purpose. When the designed the roadways and highways they did factor in a plane landing on them. They made sure that the roads were wide enough and there were enough straight sections for planes too touch down.

For the early MIG29's that is true - they had a louver system that closed off the intakes and had air sucked in through the top of the LERX. However - in the later build MIG29's they discovered the ground clearence was enough that FOD wasn't a problem and eliminated the louver system.

I never payed attention to the intake on the MiG-29s at the airshows

I read about this in popular magazine in late-80s...

Made some search, found out that the new intake design was used on MiG-29K, carrier-based version built for Tbilisi (Fleet Admiral of the Soviet Union Kuznetsov

).

Upper intakes were replaced with fuel tanks, but the intake protection was improved, at least it's what I have read here.
