A MUMMIFIED foetus has been discovered in the toilet of a plane at Madrid's international airport. Police made the gruesome find in the aircraft at Barajas' Airport Terminal 4 after it touched down in the Spanish capital from Cuba. Tests are now taking place to confirm whether the foetus is that of an ape, as investigators suspect, or is human. Respected Spanish daily El Mundo said investigators had their doubts because of the state it was in.
