context: By mid-January, Japanese advances southward cut the anticipated aircraft ferry routes to the Philippines and reinforcement was no longer feasible. Instead, using aircraft as their assembly was completed and assigning personnel at hand, provisional fighter squadrons were organized in Brisbane to assist the Royal Netherlands East Indies Army Air Force (ML-KNIL) in defending the NEI. The 17th Pursuit Squadron (Provisional) was established on 14 January, and 13 of its 17 pilots had previously been with the 24th PG. With 17 P-40s delivered by the Pensacola convoy (assembly of the 18th could not be completed because of a lack of parts), it flew across northern Australia from Brisbane to Darwin, then to Java via Penfoie Airdrome at Kupang and Den Pasar Field on Bali between 16 and 25 January. Only 12 Warhawks arrived at the designated FEAF fighter base at Mojokerto, the others lost to accidents, combat, and pilot illness.  The 20th Pursuit Squadron (Provisional), incorporating pilots of the 35th PG, took off from Darwin in 25 P-40s on 2 February, but only 17 reached Java, the remainder shot down over Bali or damaged on the ground by air raids. Likewise, 25 P-40s of the 3rd Pursuit Squadron (Provisional) departed Brisbane, but because of accidents involving novice pilots, only 18 reached Darwin on 8 February. Just nine eventually reinforced Ngoro; an entire flight of eight was lost when it exhausted its fuel after its LB-30 navigation guide aircraft became lost in a storm trying to find Koepang. Survivors of both the 3rd and 20th provisional squadrons were integrated into the 17th PS. The 33rd Pursuit Squadron (Provisional) was en route to Java at Darwin when it was nearly annihilated by a Bombing of Darwin. Of 83 P-40s assembled and flown from Brisbane, only 37 arrived at Ngoro Field, and by 15 February less than 20 could be mustered for operations.
