On good authority:
1. Wrong GPS Co-ordinates by clients?
2. Landed safely on the field at the above co-ordinates.
3. Established that had to fly to other field.
4. Restart & Normal Take-off & initial climb until some distance beyond upwind threshold.
Now speculating due to me not being there:
5. What is presumed to be a severe down draught prevented safe further climb out. OAT in excess of 30 deg C with high ground in the area and strong winds through several layers.
6. Probably Elected to do a forced/precautionary landing straight ahead.
7. Flew the plane till the touch down.
8. Post crash fire destroyed most of the aircraft forward of the firewall.
No severe injuries!
Several aircraft have been caught this way even at controlled airfields with weather services.
