MoD to buy high-flying solar planes

[Anmer]

The UK Ministry of Defence is going to acquire some high-altitude "eternal planes".

The unmanned, solar-powered aircraft, known as Zephyrs, fly above the jet streams and will stay aloft for months on end.

Designed and built in Britain, the vehicles will carry small payloads that might consist of reconnaissance cameras or communications equipment.
