Question

① what made fly boys dangerous for ww2 pilots? ② how did pilots communicate or coordinate while were in the air? ③ how did know which plane was friendly versus an enemy plane?

Explanation:

1. Flying could be dangerous for pilots due to factors like adverse weather conditions (e.g., storms, high - altitude turbulence), mechanical failures of the aircraft, and enemy attacks in a war - time context.
2. Pilots in the air communicate and coordinate using radio frequencies (e.g., VHF, UHF), visual signals (such as flashing lights or wing - waving in some cases), and pre - planned flight paths and maneuvers.
3. To distinguish friendly from enemy planes, pilots use visual identification markings (like national insignia on the aircraft), electronic identification systems (such as IFF - Identification Friend or Foe systems which transmit and receive coded signals), and intelligence about the presence of enemy or friendly forces in the area.

Answer:

1. Adverse weather, mechanical failures, enemy attacks.
2. Radio frequencies, visual signals, pre - planned maneuvers.
3. Visual identification markings, electronic identification systems, intelligence.
