Punkalouver and Pilot DAR " I was in no way suggesting you should call on the R/T evertime you stop, of course not , would be meaningless.also . I badly phrased this. should have better said " unexpectedly" instead. Anyway we do not know exactly what happenned , could be a brake failure from the P51 for all we know. That said if I was fying a P51 , (whishes, !...) I would taxi it extremely carefully and very ,very slowly , but again maybe that is also what the guy did here too. **** just happens sometimes. .
