I was sitting in the yard, eyes on the heavens, when I noticed two vapour trails that seemed to be heading for the same space in the sky.
Oh my God, there's gonna be a mid-air collision!
Then I'd be duty-bound to assist in the search for the remains of the passengers. Not to mention the remains of their wallets...
I ran in the house and googled up Flightradar24.
Turns out the plane out of the southwest was a Delta Airbus heading from Detroit to Paris.
The vapour trail coming out of the north belonged to UAL808, a Boeing 777 on a direct flight from Beijing to Washington.
You'd have to agree that mid-air collision would make for some interesting wallets.
Alas, the Boeing was flying at 39,000 feet. The Airbus was at 35,000. They had nearly a mile of vertical clearance between them as they crossed paths overhead.
But it looked promising from the ground.
