XL 112 50 Years

Remembering the very sad loss of Whirlwind HAR 10 with four crew on 20 November 1970 RIP

[Cornish Jack]

pedroalpha - Amen to that!
Yet another tragic reminder, if one were needed, that Cb and aviation don't mix well. Memory says Capt Balser (sp?) Canadian exchange, plus w/op, w/m and a WRAF. 202 out of Leconfield.

CJ, the crew (copied from the RAF Commands website):

Capt. John Balser Canadian Armed Forces (Pilot)

Master Navigator Brian Sterling (Winch operator)

F/Sgt Charles Peter Ford (Winchman)

P/O Helen Susan McLaren (Passenger)

[Cornish Jack]

Thank you, Archimedes - I didn't, personally, know any of them, but Capt Balser's name stuck from his, unfortunate, exchange deployment. I was on 1563 Flt in Akrotiri when it happened and, obviously, registered in some shock. I had been on W 10s for over 6 years and, although such losses were not unique, the circumstances were unusual.

Without wishing to stir up memories of a tragic event, could someone please post a brief description please? Ta.

Thanks digs. CJ above mentions Cb and the report says it blew up in mid air, was this a lightning strike?

I was a member of B Flight but on leave at the time. I never saw the BOI report but understand the sortie was to include dry winch training. I knew them all very well.

The effects in and around CB are now better-understood, which includes lightning, but also severe turbulence and up- and downdrafts. Enough to do catastrophic damage to aircraft both fixed-wing and rotary,

diginagain - I had a look at that report and it is a bit 'bare-bones'. From memory - local flying possibly low-level search. Low cloud base and fog/mist. In a valley with options to hover-taxi out or climb above S Alt and RTB on instruments. Climbed and found themselves in a Cb . Unable to control climb and (as we understood it) suffered catastrophic damage at 12000'. The W10 was a lovely machine to fly visually but it had NO natural stability (indeed, just the opposite) and had no stabilising add-ons such as the Wessex SAS. It was operable IMC but I wouldn't suggest it was a 'favoured platform'!

Not a place I would venture into knowingly, but the threat of inadvertent IMC with the possibility of entering an embedded CB cell does concentrate the mind.

Let us not forget the impact of icing upon an aircraft with no clearance. November in Yorkshire.
