One sunny Spring Term day in 1959 ,during the morning play break at Stopsley Junior School not one , but two Piaggio pushers heralded their first arrival with that resonating drone. Flying quite low over the school it was apparent that they were different. One was a , later to be very familiar, P166: the other ( as included in my Ian Allen ABC Continental Aircraft
) was a P136. Quite a day for a nine year old.
