When I was working I borrowed data loggers, which recorded every minute and used it a couple of times. I could tell you when the driver stopped for his supper and when he arrived at race point, as the temperature increased drastically. I believe even with the Geraldys against wicker baskets there would be no difference in heat within the baskets /crates when the the transporter stops. Yes with the newer crates in Geraldy there is 3sides for drinking, but look at the NFC And the Midland National over the last few weeks they have also suffered bad races and that's with Geraldy and similar designs. I personally believe it's a combination of radars from the major airports down that side of the country and the knowing fact of the huge Perigrine population around that area . It's a known fact at between 5am and 6 am planes are stacking up waiting to land at 6am at Gatwick and Heathrow as that's the earliest they are aloud to land .What ever happened on Saturday had very soon after liberation
