Cloudless skies are quite common in the Texas Gulf Coast region but less common over Wiltshire, England, where I grew up.
Last summer I took this shot of a British Airways 777 heading west in a cloud-free sky over the Marlborough Downs. I know it’s a British Airways plane because at 100% view, you can see the familiar BA tail markings.
Most likely this flight had left Heathrow Airport a short while earlier and was still climbing to cruising altitude, en route to the USA or Canada.
When the Concorde was flying, it too flew overhead pretty much every day but I was never able to get a clear shot of it with the gear I had back in the day. Such a shame those flights had to end.
