It was surprising if it was due to weather. Gusts of 30 kts had been reported on an earlier METAR but the latest weather was 260 at 20 kts and as you say, everything else was getting in.
He broke off the first approach at just under 2,000 ft and I wondered if there could be a technical issue. On the second approach he was down to 800 ft when he started to climb again.
After the long flight and 2 missed approaches, it was perhaps less of a surprise he was squawking 7700.if it was a fuel emergency, but I don't know if that was the reason.
It did reposition to MAN and departed about 4 hours late I believe.
