Perfect

Ed Sheeran

(...)‘Cause we were just kids
When we fell in love
Not knowing what it was
I will not give you up this time
But darling, just kiss me slow
Your heart is all I own
And in your eyes you’re holding mine

Baby, I’m dancing in the dark
With you between my arms
Barefoot on the grass
Listening to our favorite song
When you said you looked a mess
I whispered underneath my breath
But you heard it, darling
You look perfect tonight

Well I found a woman, stronger
Than anyone I know
She shares my dreams
I hope that someday I’ll share her home’(...)

Metal airplane part seems to fall from plane into Arizona family’s backyard

    An Arizona couple discovered what appeared to be a metal plate from an airplane in their backyard last week. Charlie and Jaclyn High of Phoenix found the white metal piece, which had fallen in their backyard, on Friday, CBS5 reported.
    “I kind of looked around to see if there was anything else, like another piece, or something else other than that, with writing on it. It looks like it’s from an airplane, and you think, oh man, that’s crazy,” Jaclyn told the outlet. According to images shared with CBS5, the metal piece seems to be part of the airplane lavatory.

Building on a breakthrough: Firm hoping to extend range of hydrogen-powered plane

    The firm behind the world’s first hydrogen-electric powered passenger plane flight is hoping to extend the range of the aircraft by the end of the year.
    ZeroAvia made the breakthrough by completing a 15-minute flight at an airfield in southern England last month.
    “It is not the future, it’s reality,” Sergey Kiselev, ZeroAvia’s European chief told Euronews in an interview on Thursday, referring to hydrogen-powered planes. “We are working on expanding the range of the reach of the aircraft. By the end of the year, this exact aircraft will be able to fly about 300 nautical miles.”
    It is hoped ZeroAvia’s maiden flight will be the first step in making one of the most polluting industries green.
    “The only emission from this aeroplane in flight is water vapour,” said Val Miftakhov, CEO and founder of ZeroAvia, back in September.
    “We also have a fueling infrastructure set up that ensures zero-emission production of hydrogen itself. It’s clean, it’s less noisy, and they will be able to fly without feeling guilty for flying.”

Flying with a Dog? Here’s What You Need to Know

    The choice to take your dog in the cabin with you versus traveling in the cargo hold will often be decided for you by the size of the animal and the airline’s policy. Some airlines restrict the total number of pets allowed on any given flight, and these spots are usually parceled out on a first-come, first-served basis—so you will want to book early.
    Expect to pay a fee to fly with your dog. Current standard fees range from around $75 to $200 each way, and can go up to several hundred dollars for larger dogs that must be transported on cargo planes.
    If at all possible, choose a direct flight. As tough as flying is on a dog, especially in the cargo hold, submitting them to even longer travel times plus multiple encounters with baggage handling can easily go sideways. My family flew cross-country with our dog several years ago, and had purchased direct flights, but due to aircraft problems on the way home had to switch to a connecting itinerary. During our connection in St. Louis, we watched helplessly through the airport windows as a baggage hander in St. Louis let our dog’s travel crate nearly free-fall onto the tarmac. When we ____________ at our home airport, the crate was shattered and the dog significantly traumatized.

ICE AGE

    Ice Age is an animated movie about a story that took place 20,000 thousand years ago. At that time, (I) everything was covered in ice. The movie follows the path of a mammoth, a sabertooth tiger and a sloth after they encounter an Eskimo baby and decide to protect it from the cold and other animals.
    (II) Diego, the tiger, had attacked the tribe to get the baby eskimo but was not successful. Other tigers were unhappy with Diego because of his incompetence to get the baby, who is now with Manfred, the mammoth, and Sid, the sloth. Eventually the three animals get together, although with very different agendas, and form a friendship bond while taking care of the human baby.
    The movie also features a squirrel desperately trying to bury an acorn without success. This squirrel has such a distinctive personality that we can only hope (III) he’ll star in his own movie someday.
The sentence “Diego, the tiger, had attacked the tribe to get the baby eskimo but was not successful”, from the text could be rewritten without changing the verb tense, like this:
