This is getting out of control which is a shame.If the IB crew deliberately took the risk and went with contamination,then they themselves know how lucky they were to get away with it and they will have learnt their lesson..We dont know just how much contamination was adhering to the flight control surfaces of the 340;most have assumed that there must have been significant build-up due to the fact that everyone else was de-icing and what the BA pilot said he saw.
What we do know is that the BA pilot went about it the wrong way."Yes you do" is way out of order for one professional pilot to say to another on an open frequency.Furthermore,to post it on a public forum with flight number and date is reprehensible.You can articulate your anger and/or disbelief without using specific information.The reason we're discussing this is to remind our colleagues just how important it is to de-ice if you dont have a clean wing.We didnt need to know it was IB.Instead we've got a free-for-all witch-hunt(and this is a powerful platform).And thats dangerous when the facts arent established beyond a reasonable doubt but based on hearsay and assumption.
When BA made their 3 engine record-breaking flight from LAX a while back,I dont recall any pilot saying on freq "Land the sucker".
IMHO,the only time you use an open freq to directly contradict another pilot is when you see a clear and present danger that presumably he hasnt seen.In this case,use any language you damn well please.And he'll thank you for it.But I still wouldnt post any identifying details on a public forum.
As an aside,if you saw a 737 pilot start his takeoff roll just after a 747 had lifted off(assume an ATC oversight),would you try and stop him?And would you then write about it on a public forum and give the airline,date and type and call him a cowboy?
