to your request to maintain a maximum altitude of 500
metres whilst in the vicinity of Waichao, as this
question of altitude must be left entirely to the
discretion of our Commanders. You will note, however,
that, whereas you suggest a minimum distance in a
horizontal plane of 15 miles from Waichow, our
Commanders will make every endeavour to pass not nearer
than 20 miles from the Island in question.
Under these circumstances we think you will
agree that a repetition of the incidents which we are
both anxious to avoid should not occur. We should be
very grateful if you would kindly pass the necessary
extracts from this letter to the relevant authorities.
We have the honour to be,
Sir,
Your obedient servants,
For IMPERIAL AIRWAYS (FAR EAST) LIMHED
(SGD.).
