The Royal and Ancient Golf Club of St Andrews have declared this to constitute a Movable Obstruction under Rule 24-1.
Therefore players who find their balls in the plane, ,may move the plane without penalty. If the ball moves as a result, it must be replaced without penalty. If a ball is on the plane, the ball may be lifted, the obstruction removed and the ball dropped, without penalty, on the spot directly under where the ball lay on the obstruction.
More like Pilot Officer Prune than Biggles on first impressions. Seems he was flying from Chelmsford to Kinloss in what looks like a Foxbat. That looks pretty much like a full range flight at about 520 miles, so perhaps making an emergency landing 100 miles short at Dundee was unfortunate rather than bad planning. Mind you what are fuel gauges for, or are they an optional extra on a Foxbat? Must get Rick's out for a play.
Can't help but be puzzled at why he elected to crash into trees when the golf course has hoochs of fairways to put the microlight down on - not to mention all the farmland round Dundee. Definitely puzzled at the statement that he had failed to put it down at Dundee airport. A Foxbat could land across Dundee airport (wouldn't recommend it with the higher ground behind and the river in front mind you) - not to mention all the football pitches next door - or even the car park at the former Marmalade Pot restaurant the other side.
There again perhaps he was aiming for a fairway - ended up in the tree and thought up excuse 99 while waiting to be rescued.
Edit : Oops it's a Flight Design CTSW - so much for my powers of observation.
Yeah I'm not sure I follow his logic about the tree but he certainly has a good sense of humour - evidently when the first people rolled up to assist him he asked for ladder and said he was the new branch manager. One suspects he might need that sense of humour when it comes to discussing claims with his insurers though. All the best Biggles
