The Yellow pylon mounted things are (temporarily located) aircraft airspeed probes.
oh! i was under impression that helicopters are also refueled in air like fighters. Actually when i was writing earlier post the question crept in my mind that how do they refuel helicopter considering difference in operating environment(altitude, speed etc) of a (tanker) plane and helicopter. also i never heard of any helicopter in tanker role.
a thought just came into my mind, maybe stupid. can we have IFR on a helicopter? one can modify a mi-26 size heli into tanker role and other helis can get fuel from it. it may not be useful in attack helos but definately will help in recon and AEW types of missions.
