Would it be possible to drop a plane vertically (out of another, larger plane) from high up and have it activate it's engines and fly away before it gets too near the ground, or is there no aircraft with quick enough warm-up time to beat Newton's law.

its possible.
but it would need to be an engine specifically designed for that purpose.
its also easier if the plane drops from another (say a B-52), if its not inside the bomb bay. it would be easier if it was to take off and land from the wing instead.

Given sufficient altitude, yes.

More sensibly you start the engine before the drop...

Bases on the Moon !

Personal rocketman backpacks

Touchscreen technology more than an add-on

Voice-controlled household gismos (eg curtains, vaccum cleaners etc)

recyclable plast-paper newspapers you can read underwater, and print off at a newsagents instead of them having need of deliveries

A decent postal service...oh yes, we USED to have one of those, then they 'improved' it...
