Juhu and Santa Cruz airfields.
Fareastdriver,
On 13 Dec '45, this old hand authorised himself to fly to "Santa Cruz" and on arrival clearly remembers skimming over the beach (mud flats, actually) and the sea wall onto the runway of what is now Juhu.
Explanation: the present Santa Cruz was not opened until 1948; prior to that the Bombay "airport" was Juhu, but it had commonly used the name of Santa Cruz. (Wiki: Juhu Aerodrome).
The Constellation old hand may well have flown into Juhu-Santa Cruz in earlier days, and got caught out that way.
Cheers,
Danny.
