By the way
3rd_ear, it is statements such as bolded below that tend to cause derision from the professionals on the message board.
I think it was a BA A380 (possibly flight BA282) ahead and about three 380 lengths behind and 500 feet above, an A320 or a 737 or something.
See, you have no way of knowing what the vertical separation between the aircraft is. If you'd worded your question in a less authoritative manner then the response would be much more gentle.
