I agree, Meteor III's were on the continent attacking ground targets with the 2nd TAF from January 1945 i believe, they definitely took part in Operation Clarion in Feb 1945. They nearly got a Fieseler Storch in the air, but it landed just before the cannon ripped it up.
They did strafe aircraft on the ground. It was just that the LW were AWOL so didnt get any air to air claims.
