You guys have ABSOLUTELY no idea what you're talking about!
Did you ever think, that maybe because the guy is sporting a WALES FLAG, he might be from WALES, and that he was looking at the flight operations at the largest airport in WALES, which is CARDIFF!!
Did you maybe stop and thing he was checking out the arrivals page from CWL
, where it clearly shows the information he is talking about....
A flight MAC001 from TETERBORO!!!
Why would a flight operate from TEB to CDW
, it's 10MILES!
