Further to TTN's post, I saw this on Wiki when researching the Meteor
On 7 August 1949, Meteor III,
EE397, on loan from the RAF and flown by
Flight Refuelling Ltd (FRL)
test pilot Patrick Hornidge, took off from
Tarrant Rushton and, refuelled 10 times by the Lancaster tanker, remained airborne for 12 hours and 3 minutes, receiving 2,352 gallons of fuel from the tanker in ten tanker contacts and flying an overall distance of 3,600 miles (5,800 km), achieving a new jet endurance record.
12 hours in a Meteor F3 .... he deserved a medal for that alone.
