GB, don't be too hard on BA. A few years back, I was pax on MUC-LHR 757. As we boarded, RB211's were gently windmilling with the usual clunking of the fan blades, some pax were obviously concerned and brought this to the attention of the CC.
Once airborne the Capt. came on the P.A. to allay fears, said he would send the F.O. outside to check all was ok with the engines when we reached cruise level. Everyone enjoyed a laugh.
Before descent he offered the jumpseat to any pax or wannabee who would like to view the approach to LHR. Great flight.
Pity neither of the above are acceptable any longer in our p.c. sterile environment.
