It was not unknown for messages to be sent to the other end asking if we are 'still flying' !!!
If club launchpoint/winch communications are anything to go by, there are probably still a few VGS winch drivers sitting in their winches and wondering what the delay is.
Operations with a retrieve winch need only one winch and one cable. As
Pobjoy says, the bottleneck in the launch rate will be determined other factors. I wouldn't argue against each VGS having a second main and retrieve winch in case one goes unservicable though.
I hope the people who get the French T21 down plan it so no further damage results. Fingers crossed it will be back in the air (manned this time) in the near future.
