Should have not said 'airline' but own private plane. Sister's estate not large to 'go after' (after expenses, probably $20K), so instructor's family atty may be wanting to put sister in as co-plantiff... no formal contact or paperwork yet - NTSB not through with investigation.
Plane...
Sister and instructor died in Texas airline crash while renewing qualifications. Instructor's family hired atty and going to name sister's estate in suit. Probably will be faulty equipment, but (???).
Sister had life insurance and ADD policies w/ other members of family as beneficiaries...
