Hello Everyone,
We are 70 years old glider club. Recently our airport closed down and we had to move to a much bigger airport. We agreed on the rent and moved in with 5 gliders and one tow plane. We are insured by Costello. We are already paying our rent but we just received pages of complicated contract. We could use your help with one paragraph. It appears to be that we need an other insurance top of Costello's.
1-Is this a common request? We never had to pay this before.
2-Who would you recommend for this kind of insurance?
