Below is a reply I got from NGA. It appears that some data may still
be available but a) it will be by subscription payement, b) only US
(?), c) in a different format (It costs $250 to get the format

The US airport/SUA/airway/navaid data is (and has been for many years)
available from the FAA Aeronautical Information Services Division, by
subscription:

For soaring use, 4 or 5 of the CDs would be needed at $36/CD, 6 times
per year, or roughly $1000/year. This obviously creates a logistical
problem. Someone would have to subscribe, reformat the data, and
redistribute it. SSA, maybe?
