From F G GRISLEY
Feedback’s item of 20 January about the use of Japanese satellite dishes
as navigation aids takes me back to the RAF in the mid-1950s. A radio failure
in our single-seaters in thick weather would deprive us of our main navigation
aid. We would then look out for H-type television aerials, which all pointed
at Alexandra Palace in North London.
A quick reference to the compass would give us a radial bearing from
Alexandra Palace on the map. It was then a simple matter to set a course
to intercept some prominent feature, usually a river, road or railway, and
map-read our way back to base.
Such activities in these days of airspace congestion and tight air-traffic
control would probably earn a jail sentence!
