The sound of drones taking off and landing in Moansa, Tanzania.

It's a sound that for some here in East Africa could mean a future where medicines, cash and other goods are delivered reliably even in the most remote corners.

But how far should the cargo drone concept be taken?

We're just witnessing the birth of an industry.

Imagine that the drones we have right now are something like the computers that they were playing with in

Silicon Valley in 1981. These are the machines that are going to go from a

curiosity to something standard, something standardized, something safe, something known, something quantified. This is Africa's drone experiment here on the BBC World Service with me Jane Wakefield.

An HIV sample collection from an infant who's been exposed to HIV and the delivery of that result to his or her parent and that can be up to 45 days and that's a very long time in the life of a child.

I don't really see a desire for thousands of drones whizzing over people's heads every day.

Like that doesn't sound like a relaxing environment to me.

How many types of products do you really need immediately?

That's why we focused on medical, especially blood first.

It's like somebody in his house.

It's like somebody in his house.

You open the window to get fresh air.

Sometimes you can get insects, mosquitoes coming.

So you have to make sure that you have a mechanism

that you get only fresh air.

We don't want now then terrorism or any other unlawful activities.

While drones have already revolutionized a whole range of industries from construction to entertainment

to modern warfare on the banks of Lake Victoria an ambitious new experiment in drone deliveries

could be on the cusp of becoming a reality.
