"Through the world and out the other side!" That was a figure of speech, not to be taken literally. Rather like "I'll knock you into next week" or something like that.

Walking past the Shard by London Bridge and worrying about a load of wood landing on you. There is a large crane on the roof (the Shard is Europe's tallest building), what if the crane-driver lets his sandwich go stale and it falls off. The devastation doesn't bare thinking about !wink! What if the crane driver lights a cigrarette with a match, and throws the match off the top. If is a huge distance from the top of that crane on the top of The Shard to the ground. I imagine when the match hits the tarmac it will be like the Hiroshima bomb all over again. Goodbye London !oops! Anyway, coins, sandwiches, and so on wreck cities when dropped. The destruction that a match would cause, I mean WOW!
Sorry, I'm waffling. On the issue of the person who fell out of the plane, and it was pointed out that the guy fell out of the wheel mechanisms as it approached Gatwick and was found in a field, I am sure an incident of that nature happened on the way to Heathrow too. If you go to Richmond Park in south-west London you see the planes stacking up as they are approaching Heathrow. I am sure the landing gear was opened and a guy fell out. I think he landed in the park.

I think you will find that the cab of the crane at the top of the Shard is not directly above the ground, so that any foodstuffs dropped by a driver of said lifting apparatus would slide down the sloping walls of the building rather than fall directly on to a passing pedestrian.

Last time I met her, Sandie Caine's boyfriend was a London crane operator. Only Sandie would know how careful he was with his lunchbox.

One thing I would say in favour of the builders at The Shard is that no was (as far as I know) has died building it. I remember when Canary Wharf went from one tower to three. The construction of the two new towers resulted in the deaths of several workers. The Shard, which is obviously a lot taller, has not claimed any personnel, so good on them.

It'd take a braver man than I to pick out the frivolity from the seriousness in that post, Max!

If you thought that was a threat it wasn't. I didn't mean it at you, I just thought of an expression. Here's another: "its raining cats and dogs" (pissing down outside), "I weigh a ton" (joining Weightwatchers did me little good), and so on.

In a vacuum these items will keep accelerating proportional to the gravitational force. So, if you re-build the twin towers on the surface of Mars (with not much of an atmosphere to speak of) the dropped items will be rather fast at the end.
A 100g sandwich travelling at the speed of light has a roughly the energy of 900 TeraJoule, which would be 15 times the energy of the Hiroshima bomb. Thing is though: you never get it anywhere near that speed.
On Earth it does not really work like that, at some point drag and gravitational force are in balance and the speed then remains constant.
I have heard (it might be an urban myth though) that cats can survive the fall from very tall buildings, because by spreading themselves out and increasing drag they reach their terminal velocity rather quickly.
