Dear Raafif, it seems you have started a dangerous delirium process, wild as a Mustang and violent as a Tornado...

Well, the F-52T-2 has been refused by USAAF, arguing that a Tornado is an odd phenomenon, so the number of engine must be odd (1 or 3 or 5...). North American engineers immediately proposed the 3-engined F-52U that was ordered for 10,000 copies. Alas, there were not enough engines available, and the order was changed to 5,000 F-52Z Twin-Tornado. Cancellation of this one too brought back to the famous F-82 Twin-Mustang, this is the true story of it (my psychiatrist does agree).
