It may have no bearing on this matter, but those using on-line "radar", should be aware that some of the information is derived from SBS type equipment which is certainly not fallible and aircraft are occasionally depicted in wrong positions. This is due to ADS-B not transmitting correct lat and log. Just yesterday I observed two aircraft approaching Heathrow in what appeared to be extremely dangerous conflict. A few minutes later one "landed" at Bracknell, several miles south of the true location! A/c postions on SBS can be 5 or more miles wrong so don't trust everything you see on-line.
I see no problem with post #17, but the next one was a bit off-side.
