Had got the seat 24 in Airavat KA 17 F 1572 travelling from Bangalore to shimoga. The busseemed fine but later got to know that my blower is blocked and couldn't open it. When I tried opening it greasy black powder fell all over me. Really horrible to see how ksrtc still runs 10+year old B9Rs which aren't even maintained correctly. Also what happened to the policy that ksrtc retires buses which crossed 15 lakh kms . ????
