A similar, and possibly more likely to happen, question is to do with being inside a falling lift.
Is it worth jumping up at the last second?
Another one - you are up a ladder say doing the gutters on a two storey house. The ladder starts to fall backwards. Are you better off jumping off the ladder and falling vertically, or staying on the ladder and falling in a graceful arc?

I am not sure if this has been asked before or its just my weird mind,
Say you're flying and the plane breaks apart mid flight. You are now hurtling towards the ground still strapped to your seat with the odd serving trolley passing you now and again.
Would it be possible that before you hit the ground, you can jump off your seat as though you have say, jumped off a few stairs and therefore change the speed at which you hit the ground? If that makes sense.. so basically if you're falling 120 mph whilst on a seat can you crouch on said seat and jump off it (a few feet off ground) before it hits so your actual falling rate becomes zero before you begin to fall again albeit closer to the ground.
Does the mass of the falling object you are attached to matter? Would, in theory, this work better if you were jumping off a car rather than a plane seat?
Wouldnt work. In free fall you do not retain mass of the earth to steady you only the mass of the seat you are sat in during the free fall. You may be just about able to push the seat away from you but your velocity towards the ground will be little changed and certainly not enough to save you. [b]The quicker you get out of the seat the easier it will be to climb out because as soon as velocity builds at approx 10m/s every second your pretty much stuck in the seat unless you have to power to over come physics.[b] Say you're flying and the plane breaks apart mid flight.

In Asia that's the cause of many young tourists and expat deaths. Too much alcohol and then complications which are exacerbated by dehydration.
Last night it was 29c and 50% humidity, and it's the rainy season!

So, on Great British bake off or Masterchef or some other cooking show, what happens if one of the contestants cooks/bakes something that one of the judges just doesn't like? John Torode doesn't like, say, Artichoke and someone wants to make something with this in it. Are they warned in advance? Does he have to suck it down even though he wants to go 'BLARGH! SPIT!'? Surely there must be some food he doesn't like? he can't like everything, right?

Any ideas why the rear of these row of houses have all the windows bricked up, they don't look that old
Front of houses.
Back of houses.
They are in Greenland Mews near Surrey quays in London.
This is merely a guess, but could it be to do with stopping noise from the train track right behind them?Front of houses.

Alternatively possibly a developer owned the entire row and had some kind of weird interior plan involving no natural lighting from that side.

And why are there trees and bushes painted onto the rear wall too....?Front of houses.

And why do they leave in window ledges etc?
And what are the brown 'beams'?
It all looks like an artists impression, perhaps the builders picked up the wrong plans?

Made me laugh that did. The trees are how the 3D image depicted them, obviously not painted on, beams? train lines maybeAnd why do they leave in window ledges etc?

Thanks for all your input, it's strange though.

Iam not sure if this is the case with classic car dealers (I would probably guess yes to an extent)but many classic motorcycle dealers state in their advertising 'viewing by appointment only'
any ideas why?
Because they have 50 bikes in an area the size of 4 normal garages and digging the one you want out is a pain and takes an hour.any ideas why?
Or because the bikes are all with their current owners, so the seller needs to arrange to fetch it, if for sale on consignment.
Or because they are always out fishing, so just popping in unannounced wont work.
