IGC loggers again

I am about to go away on a gliding holiday and will probably be out of touch
with any OO's. Hoping to claim the next big badge I am arranging to have my
logger sealed into the glider with a lead seal or non replaceable sealing
tape as per the guidelines on being able to operate independently of OO's.

I am now informed that 'because no-one witnesses who is in the cockpit on
any particular flight there may be a problem with claiming the badge'.

Go figure! All that effort and the logger system falls flat on its arse! I'm
still tied to an observer!
