We had a lot of speculative and unsupported allegations aired on these fora by a character called 'Safety Concerns' who appeared to be an internet voice for an outfit called AEI. The allegations began over TAP, the Portuguese carrier - at least those were the first I noticed.
I invited SC to respond to
a thread I opened in 'Questions' on 10 March to try to stop him/her contaminating the main thread running in Rumours at the time, but there has been no response. I ask you to review the lack of response and I would endorse the request to you to be cautious with this 'problem', which on the 'evidence' (not) presented to us is NOT a problem. I would also add that in my longish time in aviation we are not looking at a pandemic here.
