It seems to me that using 39 bits to number aircraft would violation
allocation density policies. See for example Section 2.8 and Section 5.2.2
of ripe-738 (https://www.ripe.net/publications/docs/ripe-738)

(unless there are 100 billion aircraft in the world).

IF the IETF directs IANA to grant this for aircraft, what happens if the
ITU shows up and wants a prefix for phone numbers?
