Cathedral of ignorance

In the print edition of The Sunday Telegraph (but not yet on-line) we are offered an extraordinarily ill-informed letter from a Mr Paddy Keenan, who disputes the claim made by Tory MP Ann Winterton last week that the slower, propeller-driven ground attack versions of the Tucano would help reduce "friendly fire" mistakes.

We take Keenan and The Sunday Telegraph apart on Defence of the Realm.
