Help fly Bill Crane home to recover

Our parents set out on their 31st anniversary trip, driving cross-country from Indianapolis to Los Angeles on Route 66. They had to turn around in New Mexico due to our dad's lung condition and they made it back to Texas before it became too severe and he had to be admitted to the ICU in Amarillo, TX 1,000 miles from family in Indiana. His condition wasn't improving enough to travel, even by car. My parents were stuck in Texas, my mom all alone with him. They arranged an air ambulance for transportation for both of them to come back home to be closer to us but their luggage had to come back via FedEx out of my mom's pocket. The cost of the air ambulance is absurd and we want to help them anyway we can. Funds raised will be used to cover their air ambulance expense as insurance won't cover it. Any help would be very appreciated to make this extremely difficult time a little easier to get through for us.
