Cubana Bristol Britannia occasionally ferried into Luton for attention by Monarch (AEL). There was at least one flight direct from Havana on 3 engines! The U/s Proteus had the prop removed and a natty temporary fairing placed over the front of the cowling. I’m afraid I don’t have any photos but those of us in ATC were most surprised when it materialised out of the murk in that condition!
