The five Angel Interceptors pilots - stationed on Cloudbase - have their own flight uniform. The uniform is unique, and they are the only ones in the Spectrum organisation wearing it.

The Angel flight uniform comes complete with a crash helmet, with part of it made of some transparent material, with the Spectrum emblem stamped on it. The equivalent of the radiocap transmitter is built within the helmet, and works the same way, with the flashing epaulettes fitted in the Angel flight uniform.  On duty, when not wearing the helmet on flight - such as when she is piloting an helicopter - the Angel pilot can use a headphone, with a transmitter very similar to that of the radio helmet.

It is unclear what is the actual rank of each Angel pilot, as like any for other Spectrum uniforms, the Angel uniform doesn't show rank. It could however be speculated that they are officers, though of an rank inferior to that of the Cloudbase Captains.

While off duty, the Angels are not bound to wear the uniform, so it's not rare to see one of them wearing fashionable clothing around Cloudbase, even in the Amber Room.
