Man I don’t miss working on the bus at all. Most people can work on a laptop just fine but not me. There’s a number of things I’ve learned I just can’t do while riding the bus and massage therapy’s one of them.
It's actually dawn, not dusk. Heading/track around 080, east, can only be sunrise. At 0730Z and with some Equal Time Points on ND, I'd say this is over the Atlantic Ocean, meaning this flight is from the Americas, probably Central or Caribbean to Europe. It's got 04h48m of flight time, so it departed around 0220Z, that's late at night in most of Central America's timezones.
With what seems to be 29 tons of fuel aboard, that's probably an A330.
Based on the 0220Z departure time, it's possible to crosscheck FR24 departure tables from main Caribbean airports, check which flights are flown with A330 leaving around 0200Z and find out the airline.
Same reason that L-shaped army flashlight has a red lens you can affix to it. You can read documents or look at a map with red light then still have your eyes’ night vision when you turn the light off.
