Air Force flags and symbols

I saw an unidentified flag flying in Lagos. It had a cyan field with national flag (Nigeria) in the canton and a kind of yellow eagle in the center.

A wild guess, but this sounds like an air force flag build on the British model.

I'd agree with Jostein's guess, however, it is still a guess. Is there any more precise description of the eagle? Does it look anything like the eagle in the crest of the national coat of arms?

I can not describe better the eagle. I only can say that it is a big one, using a big space of the flag.

I saw this flag twice, but both I was inside of a car, and Lagos is not the best place to stop the car, get out and take photos. I can not say either if the building was a military one or not. But sure it was in Victoria Island /Ikoyi areas. These areas have plenty of flags. The main governmental delegations, the federal states representations, foreign embassies/consulates, the bigger hotels and any military offices are in these areas of Lagos.
