Bowman radio kit is also sh!te. Send even more pigeons
It is interesting to note that the reverse happened. At least one carrier pigeon was carried in each RAF bomber up to November 1943 when VHF radio equipped survival dinghies became available to bomber crews. I believe that only 2 crews in dinghies were rescued due to the direct efforts of their pigeon (both pigeons got Dicken medals). Pigeons did not get airborne if wet, when there was no horizon, and when it was dark. In effect, the radio led to the loss of carrier pigeons in the RAF.
