Typhoon Ursula - September 1945 - POW ferrying

[Leendert]

Next to hostilities, accidents etc., nature also claimed lots of lives and airframe losses during WW 2. Examples are the next to complete wipe-out of B-25 equipped 340th BG due to an eruption of Mt. Vesuvius volcano (March 1944) and VMF-422 when its Corsairs ran into a Pacific storm (Jan 1944).

My question involves Typhoon Ursula, roughly between Formosa and the Philippines on 10 September 1945. Online resources speak of 6 a/c lost with some 120 men lost/missing, crews and returning POWs alike.

So far I could identify three certain losses that can be related to Typhoon Ursula: B-24s 44-40666 and 44-42052 (494th BG) and 44-40491 (11th BG).
These a/c transported 20 freed POWs each from Okinawa to Luzon.

A probable loss, but in opposite direction (to pick up POWs?), was B-24M 44-50459 of 380th BG on 9 Sept 1945. with just the crew of five.
The four mentioned a/c are covered in MACRs.

I wonder who can shed some more light where the number of 6 a/c is based on? USN transport planes to make up the number?

All info welcome, thanks.
