Then I take back everything that I said.
Thanks oxenos. Like many pilots I have always admired the Catalina and the Sunderland 'boats. We had an ex Sunderland captain on 30 Sqn, who said that you needed to know as much about seamanship as you did about airmanship to operate them. The first time I had to amend QRs was at Cranwell. A whole section dedicated to hard lying allowances, spelling out the conditions required for eligibility (ie due to adverse wx having to spend all night taxying into wind, having cast off from the moorings) had to be removed. It was the end of an era.
