Ok, apologies for my ignorance, but I'm going to ask some tenuously related questions!
When disembarking an easyjet flight last week from Glasgow to Luton, the engines were windmilling. As they turned, there was an audible "clanking" (for want of a better word!). Is this normal and if not, would it be picked up by the captain?
Secondly, on boarding a thomsonfly flight to Gran Canaria last month, we boarded at Stansted via the back door. As we walked along the length of the aircraft, the lower stetch under the wing towards the door displayed what I can only describe as "rippling". Again, is this normal ?
Sorry, hope this is ok in the "spotters corner"!
